OK. I know what you are going to say. Take him to the vet. You aren't qualified to do minor surgery and whatnot. Idiot.
A small hardish lump on his back underneath the skin about 1/2 inch in diameter, currently red but not appearing to be painful/noticeable to the dog.
I did go to the vet yesterday and the potential cost of everything was shockingly expensive. Along with the cytology sample exam, the potential cost of anesthesia and surgery cost almost as much as the dog! What really bothered me is how matter-of-fact they were with all the pricing. They even gave me the high-pressure sales pitch but saw I wasn't budging so I said I would think about it and call them back.
I know that some say a vet can numb the area and remove cysts and tumors. I also read that mast cell tumors can be treated with predisone.
I would like to know the cheapest, least intensive method if possible. I'm not cheap when it comes to my pets but since I've had pets for 20 years overall I'm tired of being put through the ringer regarding costs, my dogs have never been really sick!
Thanks for any helpful advice about what I should look for in the lump, if it possible to remove it myself with numbing anesthesia, and what a reasonable cost would be for removal if I did take him to a vet (again).
