My two year old golden Bo has been acting out of character. He's been kinda lazy-like lately. He's typically very active loves walks and playing catch outside. He hasn't been very interested in playing after about two throws he's more interested in eating grass and the whole walk he's looking for the closest grass to eat. All he wants to do is cuddle all day, and he doesn't leave my side very much and he's a bit of an explorer so this worries me. I don't know if i should try to change his food or anything else? Scheduling a vet visit asap just wondering if this has happened to any other golden owners.
