Overall the Chihuahua breed is relatively healthy. They live the longest of all the dog breeds and often make it into their twenties!
But like all dog breeds, there are some common genetic health issues in Chihuahuas that you need to be aware of.
This post will update you on all the chihuahua health problems you need to be aware of.
Eye Problems
It’s not hard to imagine why Chihuahuas may have eye problems with their large protruding eyes. Their eyes can easily get injured or get infected.
Dry eyes or Keratoconjunctivitis Sicca is another eye issue.
You may also notice tear staining under your dog’s eyes. This is normal unless you notice an odor.
An odor is a sign of infection which needs to be treated by your veterinarian.

GME ( Granulomatous Meningoencephalomyelitis)
This condition affects mostly small dogs and can cause a multitude of neurological problems including death. It’s caused by over-vaccination.
You can read more about it here: Granulomatous Meningoencephalomyelitis.
Hydrocephalus
This is a condition some Chihuahuas are born with. It is often fatal but it it’s a mild case, the Chihuahua can live a somewhat normal life.
It is a fluid build up on the brain. Read it about it here: Hydrocephalus.
Hypoglycemia
You have probably heard of this condition before since some people suffer from it. What it is, is low blood sugar.
It is most common in younger Chihuahuas and Chihuahua puppies. Basically it’s caused by the high metabolism of the young dog. It’s important to make sure your Chi eats at regular intervals.
Symptoms include muscle weakness, staggering, listlessness and in extreme cases, seizures, coma and death.
If you suspect your dog is suffering from this, rub a little honey or jelly on his gums and see if that helps. You can read more about it here: Hypoglycemia in Chihuahuas.
Kennel Cough
All dogs can get kennel cough but it’s more dangerous in small dogs like chihuahuas.
It’s highly contagious and is usually caused by the Bordetella bacteria but can also be caused by a virus too. To read more about this disease, click here: Kennel Cough.
Patella Luxation
Many dog breeds suffer from this. This condition in layman terms is simply loose knee caps. The cause of this can be genetic or can be caused by injury.
Be sure to keep you dog at a healthy weight as obesity can aggravate the condition. To read more about this condition, click here: Patella Luxation.
Reverse Sneezing
This condition is very common among small breeds. Although it sounds scary, kind of like honking. It’s usually not serious. You can read more about it here: Reverse Sneezing In Chihuahuas.
Seizures
Seizures can be serious and frightening. I have an in-depth article on them here: Seizure Disorders
Shivering
Chihuahuas tend to shiver a lot. It can be caused by several different things. The most common reason is because they are cold.
Being that their breed comes from a hot climate, they have trouble dealing with chilly temperatures.
Chihuahuas also shiver when they are stressed, excited or frightened.
Hypoglycemia can cause shivering too.
You can read more about shivering here: Chihuahua Shaking
Teeth Problems
Chihuahuas have very small mouths, which often causes dental problems with overcrowding with their teeth.
The overcrowding causes food build up in their teeth which causes decay and tooth loss.
Tracheal Collapse
In this condition, the dog’s windpipe weakens and collapses, causing the dog to chronically cough and wheeze. It can be quite serious. You can read more about it here Tracheal Collapse
Hopefully, your Chihuahua will stay healthy through out his or her life and never have any of these problems. Veterinary care is vital in keeping your fur baby healthy and happy.

January 26, 2015 at 9:30 pmHi, I am a little worried about my Chihuahua. She started to get heavy and I have been trying to be careful what I feed her. I made her dog food. I get the ground turkey and boil it. Then I puree corn, peas, greenbeans, and sometime spinach. I then add mashed up boiled egg. I also add a little dry food (for over weight dogs) and give her a supplement to be sure she gets everything she needs. She has regular visits to her Vet. Any tips that might help me. She isn’t really a big eater. I also give her occasional treats. Thanks for your time.

Sallie says
March 16, 2016 at 1:01 pmI would suggest eliminating the corn and using only grain free treats. My little Annie Beck eats about 1/4 to 1/2 cup total per day. She weighs 3.5 pounds. She has dry food for small breed available to her 24/7.
kilosmom says
March 16, 2016 at 10:56 pmGood advice Sallie.

August 1, 2018 at 7:57 pmI have the same issue, my girls are on hills science diet , metabolic..1/2 cup per day…broken down into 3 meals..with a quarter cup cheerios for bed time snack…they do well..try it. They get weighed every Saturday…weight fluctuates only by a few ounces. This diet was set for us by my vet.

August 26, 2018 at 11:03 pmI ve been cooking for my Chi since I Heard about the dogs dying from the canned dog food. I give her sweet potato she gets meat usually a good piece of sirloin or even filet mignon because I can make smaller pieces and cook as I need she gets vegetable string beans, broccoli, no corn unless it’s creamed corn she gets beans she gets, Potatoes pasta I mix of a righty of different things for her as needed but a small little half a teaspoon of pumpkin every day to keep her bowels regular she is now 15 and doctors are amazed how healthy her blood work is and how great she looks she’s not overweight at all she does get nutritional chow for neuro aging. It doesn’t take long to make things for them and keep in the fridge and the coolest place so doesn’t go bad I have a little container where I keep all her food separate they have a little compartments she needs three times a day. Hope this helps but the best thing you can do is feed her and cook for her or him as more nutrient value in it anyway then the canned crap nu

August 27, 2018 at 7:32 amI’ve been doing that a little more lately too. I split an egg among the 3 of them. And they do get a little bit of kibble too. And I take a serving of food from The Farmer’s Dog (home delivered human grade meat and veggies) and split that among the 3 of them. They love it and are doing very well on it.
kilosmom says
January 26, 2015 at 9:56 pmHi Debbie, Are you over feeding her? Chis only need 35 calories per pound of body weight a day. And that’s if they are getting some exercise too. I know for me with the dry food I feed my dog, it works out to 1/4 cup in the morning and 1/4 cup in the evening. That’s not much.
Also I think I would skip the corn and peas. They are high in carbohydrates with not a whole lot of nutrition compared to the other stuff.
Pamela Gottling says
January 27, 2015 at 10:37 amOzzy is a 4.5 pound Chi and Pom mix. I worry about his teeth. As a puppy, he had 7 teeth removed, As a 3 year old adult, his teeth are crooked and spaced unevenly. My concern is tooth decay and gum problems. He will not let me brush and his breath does not smell pretty. He eats only Wellness Core food and treats (no table food) and I use V-Oratene Drinking Water Additive (Enzymatic brushless oral solution).. He also goes for a yearly dental cleaning / exam. Is there anything else I can do to ensure he keeps his teeth (products, etc.)?
kilosmom says
January 27, 2015 at 12:35 pmIt sounds like you are doing everything you can Pamela. Does Ozzy like to chew? If so, I’d suggest getting him some chew toys and treats like Greenies, Nylabones and antlers
Mary Hegeman says
March 16, 2016 at 5:30 pmI have all four of my Chis’ teeth cleaned once a year. It’s expensive but they’re worth it! (They won’t tolerate me brushing them either, and they all use chew bones daily. It’s a breed thing.)
Olga McGuire says
January 27, 2015 at 3:09 pmMy concern is my 12 years old 2.5 pound Chihuahua has ALWAYS had a dripping/running nose. Her Vet has told me to use Children’s Benadryl, Which did work but I had noticed she just stands around a lot. So I took some and wow I was in la-la land. She has had this problem from the first day I got her which was when she was 6 months old. Her vet says her breathing is good. But now that I have stopped giving her the Benadryl she is so playful and so full of life I am wondering if I can just keep wiping her nose. When she sneezes a lot of mucus comes out. Her diet is hard food and I do cook for her, sometime ground sirloin, chicken, turkey and all with a lot of veggies. She does love her veggies. Any input would be appreciated. And I thank you for your time.
kilosmom says
January 27, 2015 at 6:46 pmI take Benadryl when I can’t sleep so I know why your Chi is in la-la land. Yeah you should be able to keep wiping her nose but if you notice it getting too dry, you might want to put a little coconut oil on it.
One thing that may be messing with her allergies is the dry food. Check to see if there are any grains in it. Dogs were never meant to eat grains and some are sensitive to it.
Debbie says
April 27, 2018 at 11:20 pmMy 10 yr old chihuahua has had a drippy nose for about 5 yrs, just watery drips. I have taken him to several doctors and they think I’m nuts because it doesn’t drip when I am there. They prescribed benadryl but I know that is strong. I give him another antihistamine when it is especially bad, mostly just at night.
Cathy says
April 28, 2018 at 6:46 pmI wonder if he’s allergic to something in your house? It sounds like it since his nose doesn’t drip when he is at the vet’s.
Debbie says
August 1, 2018 at 11:49 pmHi, Thanks! I never saw your response… His nose does drip other times when we are out. Just the few times i have taken him to the vet to explain and try to get input, it doesn´t drip.
Janet welch says
January 27, 2015 at 7:29 pmmy chi has started to get sick,vomiting, but when he does it’s just a small bit and its yellow. I changed his food and only give him sugar snap peas and carrots foe treats. He was fine for about a week, but was sick again during the night..just one time..what would be the next step..he has had X-rays and blood work. Everything came back ok.
kilosmom says
January 27, 2015 at 7:55 pmWhat did your vet say to do Janet? Something is upsetting his tummy. If it was just one time after you changed his food, maybe he’s ok now. If it continues, you may want to experiment with his food again or make his food at home where you can monitor what’s going in it.

January 28, 2015 at 3:05 amHey I’m concerned about my 9 month old Chihuahua she is 9 lbs and 9oz hey belly keeps swelling the vet had her on antibiotics and it worked for a couple of days and then her belly started to swell back up and I know she’s not pregnant because she’s a inside dog and I don’t have any male dogs so what could be wrong
kilosmom says
January 28, 2015 at 11:11 amDoes she act like she’s in any pain Amy? I can’t imagine what could be wrong but maybe it’s time for another trip to the vet.
Anonymous says
December 24, 2018 at 2:08 pmMy male chihuahua had the same problem, the vet says his liver and heart are enlarged. Please have you baby seen by a vet.
Amy says
March 16, 2016 at 9:47 pmAmy, I am Amy too! My chi was 6 months old when she started getting fat in her belly. At 9 months I took her to the vet. They thought maybe a liver shunt. Before she was 2 years old she was diagnosed with cushings disease. She drinks a ton of water and has a large belly. She is on medicine but she won’t live too much longer. She has a lot of issues. She is the youngest dog my vet has ever diagnosed. Her skin is flaky and cracking and she has lost most of her fur. She eats a lot but has lost so much weight, except in her belly, that she has no muscle mass and I can feel every bone in her back and ribs. I love her to death though. She has also lost the use of her back legs. She did have an osteotomy on her hip and she still never could walk right. Now she wears diapers. But, she is my honey and I will always take care of her. In July she will be 3 years old. Have your vet check for cushings disease.

Cathy says
January 26, 2018 at 9:57 amOMG, poor little Bobby. He definitely sounds like something major is wrong with him physically.
Ramona Rogers says
February 28, 2016 at 9:04 pmHi, my name is Mona and my Chiquaqua, Queenie, has a swollen eye. She keeps it closed. When I try to clean it, she is in a lot of pain. What do you think it is?
kilosmom says
February 28, 2016 at 9:12 pmShe could have an injury or infection Ramona. Either way she needs to see a vet as soon as possible.
Ramona Rogers says
February 28, 2016 at 9:16 pmOk, thank you so much
Christina says
March 16, 2016 at 11:26 amHi i have a 12 year old chihuahua she getting up in age. How can you tell if a tooth is loose or going to fall out.
kilosmom says
March 16, 2016 at 10:54 pmYou can feel if they are loose if your dog will let you put your finger in her mouth Christina. But really getting checked by a vet is the best way. They know what they are doing.
Joyce says
March 16, 2016 at 6:40 pmMy 5 year old long coat Chi still has his upper baby teeth. He has regular vet visits. She says she has never seen this before. Have you? What causes this ?? He has two sets of teeth on the top.One up in the gums.
patty says
September 19, 2016 at 7:24 pmThis is common with Chihuahuas. Those baby teeth need to be removed. They will destroy the adult teeth by being to close and keeping food in between the two teeth. I cant believe the vet had never seen this! Both of my chis had this and their parents and siblings had this!!
Lorrie says
March 16, 2016 at 9:50 pmMy 1 year old Chi Charlie is always shivering …..I have a doggie shirt that I put on him but he still seems to still be cold ….what can I do to help him ?
Also I feed him dog food but I also give him some people food too like for example …. cooked chicken , white rice , and the crust off my sandwich but I don’t know what the foods are that I can’t or shouldn’t feed him ….can you give me a list of the things he can’t have ?
kilosmom says
March 16, 2016 at 11:22 pmLorrie, read this article on things to keep away from your Chi. It losts a lot of the foods and other things too that are dangerous: https://ilovemychi.com/20-dangerous-things-to-keep-away-from-your-chihuahua/

kilosmom says
June 14, 2016 at 10:14 pmCheryl, my terri-poo had that and it was cancerous. She really needs to see a vet. See if you can work out a payment plan with them or try Care credit but please get her to a vet before it’s too late. We have an article on what you can do if you can’t afford vet care here: https://ilovemychi.com/what-to-do-when-you-cant-afford-vet-care/

Hengie McInnes says
April 30, 2017 at 4:46 amHi
I have 3 chi’s, one of which suffers more than the others from sinus, I manage this with homeopathic sinus tablets and it works a charm. I put one or two, depending how bad it is at the time, into a bit of peanut butter and he gobbles it up.
Another issue I have is my other chi has doubled in weight since being sterilised. I know this is common but managing her weight is really difficult especially with other dogs around. I give her 20g of pellets twice a day and add gem squash (a low calorie vegetable found in South Africa) just to fill her up. She isn’t putting on any weight but she certainly isn’t losing any. Any dieting tips for her please?
Thanks so much
kilosmom says
April 30, 2017 at 11:08 amHi Hengie, Your chubby girl sounds like me. I don’t eat much and I can go on very low calorie diets but won’t lose anything until I add exercise to it. So since you really don’t want to cut her calories any lower, you might want to add some more play time and walks to her routine. If you need ideas on playtime games, here is an article: https://ilovemychi.com/indoor-games-to-play-with-your-chihuahua/

Esperanza "Espy's" Mommy says
January 10, 2019 at 1:30 amI’m happy to see so many Chihuahua being loved dearly . My little girl had surgery yestersay shes 21 years old . I got her when I was young and didnt know the extreme importance of having her spayed regretfully she had mammery tumors and she will need one more surgery . Ive cooked for her for many years chicken boiled or baked but shes terribly picky its chicken or nothing Ive offered her almost every vegtable but shes stubborn and spoiled . Other than the tumors she has had a few teeth removed but hey shes 21 give the old girl a break . She is still spunky and playful and looks to have a grin on her face at all times . I always say if you do not know her youd never believe the sweet spirit she holds in a tiny body so much personality .I dread the day she gains her wings . Shes my heart .
Cathy says
January 10, 2019 at 8:04 amWow, 21 years old! You must be doing something right. I’m glad she got through the surgery okay.
Shyloe says
March 14, 2019 at 6:47 amI am scouring the web in search of answers to what is wrong with my little Sadie. Sadie is my 6 year old 4lb Chi. Well, she is a boney 3.5lb at the moment. She has lost a full pound in the last month or so. She eats just as ferociously as always and I’ve been as liberal with her treats as I can, but no change. This sudden weight loss with seemingly no explanation catapulted me to the vet. Other symptoms include sporadic lethargy, upset stomach, extra nervousness with yawning, stretching and paw licking. She sometimes will press her head into my hand as if it relieves some pain or indicates something I don’t understand. All of the symptoms above have been happening on and off for about a year aside from the weight loss which is recent. Also a lot of extra reverse sneezing and coughing. First vet visit we received a prescription for anxiety. This helped a little but I knew did not fix whatever was causing the trouble. Next trip (different vet) blood work revieled mild anemia and a possible infection. As finances are a concern, we treated her with an antibiotic but did not locate the source of infection. She responded beautifully and seemed back to her old self until about a month ago . We returned to the vet and found she lost 1 pound since her vusit 9 months ago. Physical exam is good and blood work shows a slightly elevated white count but did not concern the vet. They gave her an antienflamatory which doesnt seem to be helping. I can’t bare to see her sad and so thin but I also can’t afford to keep going to the vet for nothing. I am hoping someone might be able to shed some light on these strange and concerning symptoms.
Cathy says
March 14, 2019 at 9:23 amSadie is such a cute little girl!
I can understand your frustration and worry. She sure has a lot of different symptoms. I wish I had the answers for you.
One thing really concerning is the head pressing. That can indicate a neural problem or some kind of toxic poisoning. Does your vet know about the head pressing?
