Our dog is going on 10 years old and started limping. We noticed he had a large mass under his shoulder and a few smaller masses on his paw and side. We brought him to the vet and they were concerned that these masses were suspicious. We made arrangements right away for our dog to get these masses removed. Fortunately, they were fatty masses and he no longer limps. We submitted the Vet Bills to Aspca and it was followed up and processed within 4 weeks. The insurance really helped us a lot.
