We have had quite a few Tamaskan dogs suffer from allergies to dairy, eggs, gluten and wheat over the past few years.
If your dog is suffering with stomach problems then I suggest you change the diet until you find one to suit or ask your vet about intolerance tests.

I think Jasper might be allergic to eggs. I tried adding an egg to his kibble every morning for a couple of days as a treat and he really enjoyed eating it but each day he had terrible diarrhea. Really bad. Since I stopped giving him eggs he's been fine. Has anyone else had the same problem?

Yes there is someone in Finland with a Tamaskan who is also allergic to eggs.

Yes it was but with a process of elimination they found what was causing it and have now changed the diet and all is well.

Juneau chews his paws. No grains in his kibble. There are eggs. He didn't start doing this until several months ago. I have also been told they do this out of boredom. Any suggestions? I even think he may be allergic to grass. He doesn't like to step into it, especially when it's wet! He is too silly for words.

Luna used to be terrible for chewing her paws.
The vet did say he thought it could be some form of hayfever, there are products for them around the internet, you could try them out.
Bitter apple spray also used to help her stop chewing, but it wasn't a cure for the itch.....
