Adult Height at Shoulder:
14-15 yrs or more
Both the Short Coat and Long Coats are easy to groom.
Brush using a slicker brush or fine toothed comb frequently as they can shed an average amount of hair and shampoo when necessary.
They are intelligent, learn quickly, and respond well to proper, gentle training.
They are easy to house train especially to paper.
They do not respond well to a teasing child.
Many Chihuahuas are born with an open fontanel. This occurs when the bones of the head do not fuse together and leave an open or “soft spot” on the top of the head (much like a human baby), most close up within the first year or 2 of life while others can remain open thoughout their lives. This doesn't usually cause any problems and dogs with this can lead perfectly happy, healthy lives.
Luxation of the Patella (dislocation of the knneecap) is a common problem with chihuahua's & other small breeds.
It is not unusual for Chihuahua's to have ocassional bouts of sneezing, snorting or honking. Although it be scary, it usually only lasts for a short time & most times can be ended by massaging their neck & encouring them to swallow or lick. Another way is to clap to distract them.
Because Chihuahua's are so small, they can be prone to "Hypoglycemia" which is a condition where the blood sugar level drops, much like an diabetic. It can be caused by stress, illness or lack of food. If you notice syptoms such as weakness or seizures place glucose straight into the dogs mouth and get straight to a vet, keep giving the dog glucose until it returns to normal. You can help prevent this from happening by putting glucose into the dogs drinking water, especially while its young.
Chihuahua's, especially Long coats can lose there coat around 4-6 months of age, don't worry it will grow it back. I have found that unusual colours such as blues and chocolates are more prone to do this.
Chihuahuas hate the cold and may shiver; they appreciates a doggy coat on cooler days.
They are well suited to any sort of living conditions such as apartments or house; they do not require a large back yard.
