Took the 6 weeks free pet insurance just for peace of mind as Peri I was going to be a large dog. At his initial vet check everything was fine. By his second lot of jags they thought the possibility of a heart murmur. A couple of months after that, he had an ultra sound and they found a 4 mm hole is his heart. Thankful this has not caused any further problems but we know we have the insurance in place so he will be taken care of.
