I think Kash and Ozzy are soul brothers
Ozzy is right around Kashes age and he was neutered May 6th and he had no adult teeth in yet either. 2 days or so after his surgery all the little front teeth fell out on the bottom. He now has double canines on the top. This week his bottom canines fell out and he is mouthing alot so I'm hoping that the tops are coming out soon. Definately give him some more time. My vet said wait for a few more months to see if the adult teeth push out the baby.
