A lot of times it's recommended to go with the opposite gender of the dog you have, but every dog has its own personality. Our Basenji mix is a boy and we decided another boy would be fine for us because Koi isn't dominant or submissive, he just likes to play! Introducing them well and keeping them separated when needed helped. They love being together now!
If you're getting a puppy around that age then it will be much easier for them to learn to coexist. Also be sure you pick a more docile puppy and not one that's a little more high energy. Introduce them on neutral ground like at a park and let them sniff and greet before bringing new pup inside. |
