We lost our sweet 15-year-old rat terrier this week and our hearts are broken, of course. He was such a perfect friend. We got him when he was 9 1/2 months old from a backyard breeder who claimed he was full rat terrier. I met his dad, and he was a small guy, definitely a rat terrier. I didn't meet his mom, but saw a photo and she looked much bigger and much more like a basenji. He loved to snuggle under blankets, was a little grumpy on waking, somewhat aloof, but very affectionate, groomed himself like a cat each night. We eventually want another dog, and would love another whatever he was. Do the experts here think he could have some basenji in him, or is he most likely full rat terrier? I'll post a few pictures.
