My dog (he's small, about 15 pounds) is male, a mutt, about 6 years old and we brought him into our house as a puppy when we still had three cats (and he got along with them fine, but we only have one cat now).
There are two dogs I'm looking at for adoption; a male 3 month old Chihuahua (possible mix) and a female 2 year old Papillon mix.
Which would be better gender wise? How about age wise? Or does it not make a difference? Any tips/suggestions for me?
