After getting great advice on YT, I have decided to spay my little 2lb 8oz Fiona. I am currently switching her food to Blue Buffalo and plan to start her on fish oil after her spay. Members have told me that the fish oil increases the clotting time so I should not use it before her surgery. I am hoping that the food I chose has fish oil and other great stuff in it and I was wondering will the food cause the same effect that the oil would? Is there enough to make a difference? Hope there is enough to help her coat and skin and not change her blood.
