Oh, there is one little issue. His current dog (male btw) has continence issues. I'm thinking maybe a younger dog might take his lead IYSWIM and he would end up with two dogs pooing in the house.
He got his current dog from a rescue centre, and he will be going back to that one to look for another one.
I must admit, I'm a little worried about it tbh. He works longish hours, and I believe his main motivation for getting another dog is because he thinks his dog is lonely. DB has been away for a few weeks, so his dog has been staying with a friend, who has a dog, and DB's dog has been having the time of his life. He clearly enjoys the company, but I think he also enjoys the space. DB lives in a flat (it's a big flat), and the friend lives in a house with a big garden.
Fortunately for my brother (and his dog, I suppose), he lives above where he works, so he can check in on the dog, and he's close enough to take him for walks on his breaks. However, his dog still does get a bit lonesome (I feel I should add that he got the dog when he was with his ex-gf, and she had more time to spare, so it wasn't the case that he got a dog he knew would be alone a lot during the day)
Part of me thinks that he doesn't realise that two dogs means more work, not less. Fine, they will keep each other occupied, but they will still want affection from him.
