Getting a dog spayed

Question
I was wondering if you'd be able to tell me an approximate amount that it would cost me to get my female black lab fixed. We live in a neighborhood that has a few stray/loose dogs and I don't want her to be beckoning them when she is in heat. Also, with this specific breed, I was wondering if there are any particular health problems that are known among this breed. Thanks so much.  

Answer
it depends on the area you live in for cost.

DO NOT SKIMP ON A SPAY COST. Find out what you get in the cost, such as bloodwork (which absoloutly should be done before hand) an IV catherter, and IV fluids during the procedure, before and after and to go home pain managment too!)

Labs are prone too:

hip dysplaysia
degenerative joint disease
obesity
lipoma tumors
cushings disease
hypothyroidism
periodontal disease
etc...

lots of stuff! :)
