Tamara, Phred recommended these to me, and I got a Bite-Not collar for Star -they are the best! No freak-outs because it doesn't interfere with their vision.

I called the company, VetAmerica, and they DO ship to Canada. Also, they had the lowest prices of all the sites I looked at. (about 25% lower!)
Here is their link to the Bite-Not collar page:

Now...you do have to cinch it up pretty tight - my very clever husky has managed to slip out of it a couple times. Not a problem, though, cause the shoulder/belly strap kept it from falling off and becoming a chew toy. They're washable & mine is holding up well after multiple uses. (for hot spots ) Hope Anvik is being a good boy!
