Best dog coat: Great White North Winter Coat (Chilly Dogs)
Best dog ID tag: CollarTag (Boomerang Tags)
The CollarTag slides onto your dog's collar, and is unconditionally guaranteed. I personally hate the sound of jingling tags, so these are great because they make no noise! It is made out of bent stainless steel, and the engraving is of the highest quality. The company also makes the best plastic and stainless steel regular ID tags. The CollarTag is $10.20, the plastic and stainless steel tags are $9.20, and they all ship for free.
Best natural dog chew: Antlers (Antler Pantry)
Antlers are the best chew I've ever found for my hard chewing dogs. Deer, elk and moose naturally shed their antlers and they are then foraged in the woods by the vendor. They don't smell, don't splinter, aren't greasy and last forever. I don't buy antlers in a pet store because they are small and ridiculously expensive. I found a website that sells antlers at a fantastic price and you can buy them split with the marrow exposed, or whole. I've found that my dogs love both, but the whole ones last longer. I have an antler in every room of my apartment.
Best dog insurance: Trupanion
I've had several insurance policies for my dogs, and Trupanion is the best out of all of them. 90% reimbursement with no cap or payout limits. When your vet bill is in thousands, it makes all the difference.
