So lately I’ve been thinking about getting another dog. My current dog is a Chihuahua and possibly Rat terrier mix; he’s about 13 years old. Before I got him he used to have another chihuahua he always hung around with, but that was when he was around five. He only barks when there is someone making noise outside or that get too close to our fence, the same goes with barking dogs or ones that pass by our house. Other than that he is very friendly with strangers, especially when they come into our yard. He does however, have an issue if dogs come onto his territory, like most dogs do. He has never been to a dog park and has gone to a pet store a couple times, either for shopping or to be groomed. Our neighbors have a dog who barks at everyone and everything, even if I open the back door for a second. My dog occasionally fights with him through the fence, and by that maybe every few weeks. My dog doesn’t bite, growl, nip, scratch or anything at strangers when they come over, even if it’s our pest control. I’m not sure how he will react when we bring another puppy home? We’re either thinking of getting a border collie, lab, doberman pinscher or possibly an italian greyhound. Any tips on what to do when they first meet? Do you think he’ll be alright with another puppy? Any advice helps, thank you!!
