I only have 1 goat and he is perfectly fine by himself! We had a nanny, then 2 kids also, gave the nanny and one kid away and the other died, so he has just been alone ever since. But does really well. he can see our horses across the driveway and we play with him daily. Some people said I have too much time on my hands because I trained him to jump up onto a stump to get a treat and all four feet have to be on the stump! lol I have to admit I do spend alot of time with him, so I guess I am his herd. Hubby and I had a disagreement about putting him in with the dogs, but we have a full blooded german shepard and a shepard/rottie mix.... so I win, he will not be put in with the dogs! I think it would depend on the size of the goat and the breed of the dogs. Just my opinion.
