Oh, he's a cutie!!
Does he do that 6-feet up, all four paws off the ground thing when you get home?
We have a dog that does that!
Always makes me laugh...
I'm sorry you got some not-so-good news
But they'll know more once they get the thing removed and can do a decent biopsy of it. Maybe it'll turn out better than you expect
Regardless, you'll be in our thoughts and prayers!
