Chihuahuas

The smallest dog breed is the chihuahua; the Yorkshire terrier is almost just as small.

While the title of "tallest dog" traditonally goes to the Irish Wolfhound, two other giant breeds are probably just as tall: the Great Dane and the Hungarian Kuvaz. Standing on their hind legs, all three of these breeds commonly reach 6 feet or more.

The heaviest dog is the English mastiff, at almost 300 pounds.

Big ears if a teacup very small! big eyes and tiny tales.

Yes all dogs are descendents of the grey wolf. Domesticated dogs (purebred dogs specifically) have been deliberately bred over time to maintain certain characteristics such as size, temperment, etc.
Unfortunitly, yes. The tiny [barely a] dog is a far descendant of the gray wolf.

yes

Yes if he/she is a full blooded chihuahua if a mixed breed than it might not be to much.Does the dog look overweight?if so call your vet and ask what you can feed the dog so it will lose weight.

I'm actually going to answer how fast can chihuahuas run. I'm only ten and I know I run as fast as 21mph-28mph.I run a little faster than my 4 month old chihuahua "Buckie",so I'm thinking full grown chihuahuas can run from 18-20mph.

Step 1. Get paper and pencil. Step 2. Look it up on GOOGLE. :)

That all depends on how much you spoil it...but if you want to do good and save tons of money at the same time, ADOPT a chihuahua. Go to Petfinder.com and you will find a wide range of chihuahuas. They are all located in shelters and really need homes. Most of the time when you adopt a rescued pet, you get food and/or medicine to go with it.

We call ours a "Jack Shitz"! (Minus the z...it wouldn't let me use the word without the z.

for such a small dog it should be only a couple times so you don't for one get her thinking that is the only reason you have her. and for health reasons too it is not good to breed a dog a lot because like us it wears down on their bones and health.

Chihuahuas mostly only hail from Mexico.They also parshley originate from China.I've read it in the Essential Chihuahua that chihuahuas are a breed cross of a Chinese dog and a ancient aztect dog. I strongly suggest that book to get good information from.

Some periods can be as short as 3 days while others could be a week or two. I've heard of one instance where a girls period went for 26 days! However periods usually last on average about 5-7 days.

They do everything you want them to do without complaining. They never lie; and always do homework and turn it in on time. I should know, I'm an 11 year old girl.

If a female, it might be her hormones, Or lack of nutritional food.. Best to check with your vet..

Nothing actually! Almost all of the toys we Americans have are made in China! Only about 2/8 of the things are made here, and most of it is technology. Any way, the difference between American and Chinese toys are that the ones made in America you can be proud of and know that they do not have lead in them! :)

Just as you would train any other dog, with a little time, love, and patience. Chihuahuas are not as hard to train as one would think. You can purchase "how to" books at many stores including Petco and Petsmart.

The same New York, New York has: It is a city which also happens to have the same name of the state where it is located.

yes they are very sensitive

Good question, the answers is no. Some dogs go into heat twice a year and others only one. Chihuahuas go into heat twice but in 6 month intervals. It is highly recommended to consult your vet ASAP to have a look if you think it is going into heat because of vaginal bleeding. this could be a result of a genetic disorder, vaginal infection or injury all of which can cause your dog to be in great discomfort and the latter two can be deadly if not treated with care.

It is normal chihuahuas usually shakes and it could be hot.

If you want them to die. Coffee is toxic for dogs.

It could be one of many things such as his bladder or urethra, a UTI, kidneys, prostate it is important he have more indepth tests done as to not worsen his condition especially since it has be going on for 3 months that is way to long and could be fatal for your puppy - he must be sad and uncomfortable you must take him to the vet or give him to someone who will take care of him.

Also check for any plant or home cleaning liquids that the dog may be licking. Many toxics may produce that reaction.

I had a similar problem some dogs just don't like collars try using a harness.
