Mass removal on Hendrix left hind leg

My dog’s name is Hendrix and for the past several months he has had a knot on his leg that is getting bigger. We went to the vet for a needle aspiration to find out if it was just a fatty tumor that some dogs get when they’re up in age. We was told at the time it was not a fatty tumor and since the origin was unknown it needed to be removed.

As his mom I’m devastated that I can’t afford this surgery on my own and is humbly asking for small donations to collect the amount for his surgery.
