We got a second pit after we heard a tragic story about two dogs getting put down. We took one and the other went to another family. It’s been about 2 months now and the pits (mine and the new one) love each other. We will find them cuddling when we walk into a room.
We have noticed that the first one we got (we had her for 1yr before getting the second) has become “wiser” now. We think she is acting as a mama to the second. They both behave very well and we hadn’t even noticed how far we had come with training until we got a second. I think they see what is bad/good by how we react to the other.
Definitely get a second, although training is always a challenge, if you have one dog already trained, it really helps. I wish you the best of luck with your pits.
ps. Both dogs are female and neutered and are about 4months apart in age.
