Medical Help Needed For Senior Dog

Poor old 12 year old Murphy is a new yorkie surrender to our rescue who is in desperat need of a full make over and we need your help to make is happen. He is a cryptorchid which means he only has 1 testicle desended so needs full surgery to find and remove the missing testicle. He has a massive cystic mass on his lumbar back area that needs to be removed. He needs a dental with a few teeth removed. Plus blood work to make sure at 12 he is cleared for surgery. This poor boy needs a lot and we would love to get it all done at once then have to put him under anesthesia multiple times. We would appreciate any help financially to get this done. Thank you so much.
