My dog not only has food allergies, but also suffers from arthritis (she is a Labrador Retriever after all).
We have tried to use certain joint supplements before, but they all produced heavy allergic reaction in my dog. In fact - that is how we pinpointed that she was very allergic to beef proteins.
My vet who, is an expert in allergies, found something based on a type of shellfish. It's a mussel called perna (perna canaliculus) which contains high concentration of glycosaminoglycans (GAGs) - about 12%. It also contains anti-inflammatory compounds making it ideal for dogs with joint problems.

As a responsible dog owners we all want the best for our pooch. When it comes to food – I am particularly interested. My Lab has food allergies and choosing the right food has been a challenge over the years.
According to this article – expensive pet food is not better than cheap pet food.
“When it comes to buying pet food, higher cost doesn’t always mean higher quality, according to the March issue of Consumer Reports. A higher price could indicate better ingredients and better quality control during and after manufacturing, but it could also just mean prettier packaging, more marketing, or a fancy name. And despite food safety concerns that resulted from a recall of pet food tainted with melamine in 2007, Consumer Reports urges caution for consumers who are considering making their own pet food, a growing trend.”
