We lost our last 5 yr old English lab to an unknown illness. Looked like lymes but tested negative for that and all tick borne diseases. All tests and scans showed nothing but he continued to waste away. The vets were all stumped. Then just 6 months later our 17 year old Jack Russel passed. So we are dogless and taking our time healing. We've had 7 labs over the years. Each with strengths and personalities all their own. This last one was so special I'm afraid he will be the one all future labs are compared to. So we take our time. But duck hunting season is upon us and we miss our enthusiastic pal.
