Help Lester Smile

2.5 years ago I rescued Lester after he was found walking around Queens with no leash or collar. At the time, he was 10 years old and he had to get 22 teeth removed because his previous owner did not take care of him properly. Today I took Lester back to the vet, and we are told he needs to get more of his teeth removed. The doctor says Lester is definitely uncomfortable, as he  hasn't been eating, has bad breath, licks alot , and is constantly rubbing his mouth with his paws. 

I usually don't like asking for help, but Lester really needs this surgery.  Anyone who knows me is well aware that Lester is my absolute world, and there is nothing I wouldn't do for him. He's like a son to me. Any support would be extremely appreciated by Lester, myself, and all of his loved ones.
