S.V.
I used to be a veterinary technician and have worked at several hospitals from Long Beach, to West LA to Whittier. The closest I worked at to you would be Whittier, its Washington Blvd Animal Hospital on Whittier Blvd/Lambert near Presbyterian Hospital. The 2 doctors that I would recommed are Dr. Voorheis and Dr. Throgmorton, they are both very caring and understanding doctors and I continue to take my 2 babies to them. Dr. Voorheis just did a bladder surgery on my dog not too long ago.
Cancer can be a very hard and painful thing for both you and your dog. Dr. Voorheis will "tell you like it is" regarding what to do. Jusst be prepared that the treatment is VERY expensive if you decide to to Chemo. Some places even do radiation, but not there. Good luck and let me know how things go.
