We've got a rescue puppy who we've had for three months. He has anxiety which we have been working on with training, plug in and supplements for his food and finally this week he seemed ready for daycare. Our secret weapon has always been other dogs as he is not nearly as anxious with humans when dogs are around, so when he went for his trial he flourished and started playing straight away. He went for his first full day yesterday and when we picked him up they said they couldn't have him back. Apparently he peed on all the other dogs, I didn't even know that was a thing! I know he's hit puberty and has become a bit unruly since that happened, but this extreme marking only started ironically after his puppy training class on Monday night. The class was so stressful because although I asked people not to approach him, the guy next to us and the assistant trainer insisted on trying to win him over. He comes round eventually but on his terms, the whole direct approach was too intimidating for him and I'm not sure if this was the catalyst for the week. I could be way off though, it could be just part of a hot mess week, because would his anxiety make him pee on other dogs, as everything I've read said that points to dominance? After the class he was hyper, nipping me, ripping paper and barking, then the following day he peed twice in various places then the following day at daycare. How can I socialise him and get him over the anxiety with people when he's started peeing on everything, including dogs! Any advice, experience would be appreciated.
