Pug He has Cherry eye but it doesn’t

Bubba is a pug cairn! He has Cherry eye but it doesn’t cause discomfort or pain, only cosmetic. He is one and a half years old with his neuter and shots. He is a very loving and cuddly boy, he tries very hard to listen. He knows sit, stay, and kind of shake. Bubba has separation anxiety and will bark for about 10 minutes after you leave. He does eventually stop, however it takes a second. He is potty trained. He will growl and bark at men but he’s never bitten anyone. He just gets scared. You must tell him “no” when he starts to bark, or he won’t stop for a bit. He has had accidents while left alone.
