I have a 5 year old male boxer and my friend has asked whether we would have her cocapoo who is also 5 male. I have 3 older boys who love dogs but I am just worried about the dynamics whether my boxer will like the other dog. My boxer has not been neutered . Will the other dog have separation issues . I don’t know much about the dog apart from I have been told he is a real sweetie . Is 2 dogs a good idea or bad ? Experiences please thank you
