HEALTH V. SIZE
Health
I don't think tiny dogs are prone to more health problem IF you get them from a reputable breeder. Hypoglycemia (low blood sugar) may be an issue but they shouldn't have any genetic problems if they were bred well. My tiny (1 lb and 2 oz) Chihuahua is extremely healthy because she was bred well.

Just be aware that they can get hurt more easily. My Chihuahua, Cali, can not jump on the couch by herself and can NEVER jump off the couch. In fact, once she was playing with Tia and she accidentally fell off and she SCREAMED!! Have you ever heard a dog scream before? Take it from me, it's a god-awful sound and it just about broke my heart! We rushed her to the emergency vet (I won't even tell you what it cost) and after x-rays and an exam, she was totally fine. She was just sore from the fall (thank god there was nothing else wrong with her). |
