Forgot to say he also goes to an enclosed dog run a few times a week.
Thank you so much greysmom, I have been looking into daycare as an option to further give him stimulation and also socialisation with other dogs.
Hadn't thought about a muzzle, is it okay to muzzle him and not my older dog though?
My older dog is definitely a wimpy whippet, he has become afraid of him and won't stick up for himself. I don't want this. When these events happen it's very difficult to manage as I'm trying to protect my older dog but also myself and he lunges, growls, barks and tries to bite us both. I have already started giving my older dog his dinner, etc first as I know this is important in terms of pack.
I will look into the programme as an option just in case it's needed thanks.
Yes your right, puppies can be both and he is, I haven't experienced this before in all my years of owning dogs that's why I thought I'd reach out. We did have another rescue dog (whippet) that we got when my older dog was a pup and it went so smoothly she was an older dog and warned him the first day she came and then they got on so well until she had to be put to sleep. We waited a good few years and thought it might be good for him to have some company again.
