Get a free health exam from your local VCA vet office. Go here for more information. Personally, I try to avoid larger chain vet offices. They are typically more expensive than local pet hospitals. I konw this from personal experience. I originally took my dog to a large chain vet and the visit alone was $20 more than what I pay now at my vet's office. I did not have a great experience either at the large chain. However, if you are concerned about something go on with your pet this might be a great way to get that checked out. However, do be aware that this only covers the exam, not any treatment services.
