My wife and I found a stray dog(pit bull mix) and we decide to keep it after going 2 weeks without being able to locate the owner. He’s such a sweet and loving dog but he has some issues. First, he cries a lot and barks when we leave him. Figured he has some sort of separation anxiety. He goes crazy when he’s left alone. It initially continues for a little while but then calms downs after a while. However, the he gets supers destructive when he is first left alone while he is crying, whining and barking. How can I fix this or what are she suggestions to help with this? He’s so loud.
