Check out our main post that showcases all our chihuahua fact articles!

Are Chihuahuas Mean?

Well, they can be. Any dog can be and chihuahuas are no exception.

It all depends on nature and nurture. 

Chihuahuas have been over-bred over the years and because of that, some of them have not so nice personalities. 

And some, just haven’t received the proper training. 

I can tell you though, there are many sweet, good-natured chihuahuas out there. My two are so sweet, they don’t have a mean bone in their wee little bodies.

Are Chihuahuas Good With Kids?

They are best with older kids. Small children can be a little too rough on these tiny dogs. Not meaning too, they may accidentally hurt them.

And chihuahuas can bite the child out of fear of getting hurt.

Are Chihuahuas Related to Wolves?

All dogs are related to wolves. Hard to believe chihuahuas are too but they are. 

They also may be related to Fennic foxes too.

Are Chihuahuas from Mexico?

Yes, it is believed they originated in Chihuahua Mexico, hence the name.

When do Chihuahuas’ Ears Stand Up?

They should be up by the time your chihuahua puppy is 9 months old. If they are not up by then, they probably will never stand up.

Some chihuahuas do have floppy ears their entire life, but are still pure bred chihuahuas.

When do Chihuahuas Stop Growing?

Chihuahuas do most of their growing in their first 6 months.

From 6 to 12 months, they will continue to grow, but at much slower rate.

Usually by 10 to 12 months, they are as tall as they are going to get. They may fill out some more over the next year though.

Why do Chihuahuas Burrow?

Chihuahuas tend to love to burrow much more than other breeds. 

Burrowing makes them feel safe and snug. It also adds extra warmth, which chis need.

Are Chihuahuas Smart?

Overall yes they can be quite intelligent. They do have the largest brain size in relation to body size.

But as I mentioned earlier, the breed has been over bred with unscrupulous puppy mill breeders so in some cases their intelligence has been diluted due to years of bad breeding practices.

Are Chihuahuas Hypoallergenic?

No, according to the AKC  Chihuahuas are not on the list of dogs that are hypoallergenic.

You can lessen their allergy stimulating dander by brushing them daily and bathing every few weeks.

Are Chihuahuas Good Family Dogs?

Chihuahuas can be good family dogs but they do better with one or two people.

Can Chihuahuas Be House trained? 

Yes, but it isn’t always easy. Potty training issues seems to be the biggest complaint I hear from pet parents.

It can be done with consistency and determination.

Are Chihuahuas Loyal?

Chihuahuas are known for their loyalty. They usually pick one person in the household who is “their human”. They may love everyone in the house but are extremely loyal to their human.

Are Chihuahuas Aggressive?

Yes, they can be. Some chihuahuas do seem to have a Napoleon complex.

They see themselves as much bigger and tougher than they really are.

Proper training from an early age is a necessity with these little guys to keep them from getting out of line.

Why do Chihuahuas Bark So Much?

Chihuahuas bark a lot for different reasons: to warn you of something, out of boredom and frustration, out of fear (being loud makes them feel tougher), and out of habit.

They make great watch dogs though. Nobody is going to get into your house without them telling you about it.

So have you had any of these questions yourself? Or have other people asked you any of them?

Is It better to have two Chis?

In many cases yes. They are very social and if you can't be with them all the time, another small dog really helps them.

I just found out my Chi has conjestive Heart Failure . Do you have any information on this condition. She is only 10 years!


Monday 29th of July 2019

I haven't written an article about this but plan to. I've had a little experience with CHF as my mother had it almost 10 years before she passed and my first chi Kilo had it too and lived several good years with it before she passed. I like this article about CHF:

I have a rescue part chi that is about 15 years old. He itches all the time and scratches constantly. He has seizures and is on Phenobaritol for that. He will lift up his leg to peepee and scratch instead. It is really getting on my nerves. I have even considered letting him go on the rainbow stairway to doggie heaven. The Vet has tried steriod shot. Did not help. When the weather gets cold, this goes away, but every spring and summer, the itching and scratching begins. He has had a flea treatment because of fleas, but the scratching still goes on. I feel like his quality of life is gone and mine is going. I am 85 years old and this is really bothering me, but I love this dog and don't want him to suffer. Does anyone have any thoughts that will help me decide what to do.

What are you feeding him? My boy Chihuahua (Neekie) and my Husky (Leiska) are both allergic to Chicken dry food (they can eat regular chicken for humans). Both get terribly itchy and scratch to the point of hotspots. The food that works the best for both of them has been American Journey Salmon and brown rice (or Salmon and Sweet Potato). We buy this from Although lately we tried American Journey's Rainbow Trout and Herring which has proven to be a huge hit here. Both work great to keep the weight down on our two Chihuahuas who have a tendency to gain weight too much. So perhaps a diet change will help him.

Oh wow, Peggy, that's a tough one. It's definitely seasonal allergies but I'm not sure what you can do to help him. Want me to ask in our Facebook group? Maybe someone there will have some suggestions for you.

Actually both of my fur-babies are barkers. I have a chihuahua and a Boston-rat terrier. But I can't be too upset with them because my neighbor comes and goes alot and gets slot of visitors.

What a beautiful chi Laura. Love her coloring.

Saturday 27th of July 2019

She may be in pain. I would have her checked by the vet to make sure she doesn't have arthritis or something else bothering her. I have 1 that will be 12 in August. So far no problems.


Saturday 27th of July 2019

I agree. If this is a new thing, she may be hurting and that's why she doesn't want it on. I love that pic of her. She's a cutie!
