My husband and I went to the pet store today and we saw the cuttest Chihuahua, it's one of the smaller ones w/the bigger heads. Well, we absolutely fell in love with him!! However, we decided to do our homework first! SOooo, what are the pro's and con's on these adorable creatures? Any advise would help! Oh, I should mention, I do have a 6 month old Beagle (Scrappy) and a 2 yr old Miniature pincher. We probably won't get him till maybe 3 months or so, unless we find an affordable one!! Thanks for your help in advance!
