We just now notice it!

We can't deny that our dog Bullwinkle is getting old. He is showing to much of character as an old one. He's eyes got kinda gray, he got white hair on his eye lashes and eye brows, he doesn't get too excited as much as when I first move here 3 years ago and now to our surprise, he is losing his teeth!!!! We just noticed it earlier that he lost his upper front tooth and the next toot beside is ready to come out. We didn't get bully as a puppy and he was only found but his old owner never claim when my hubby try to post his pictures so anybody can see him to let the owner know and will come and get him. The vet said when they got him, he is about 3 or 4 years old, so now he's about 9 to 11 years old (we don't now fr sure). He is a good doggie and I hate to think that he is getting old too fast :(
