#4 A Chihuahua should never appear shy and nervous. He is docile and watchful.
He knows how to assert himself even against much larger dogs. He's not a spoiled dwarf, but a pocket-sized canine personality.
#5 Cuddling is one of his best exercises, and he fully adapts to his partner, whom he jealously protects.
So it is an ideal companion for people who are limited to a small living space and spend a lot of time and love for their little friend. A dubious breed characteristic is an open skullcap (fontanelle), but it is no longer required and should be as small as possible.
#6 How cold is too cold for a Chihuahua?
According to intermountainpet.com, small dogs like Chihuahuas and Yorkshire Terriers can typically deal with temperatures between 50 and 60 degrees. Owners should keep an eye on their dogs to see how they react to temperatures below that threshold.
