Calm Paws Basic Inflatable Dog Collar
Well I took a wild guess that my friends dog 40 lbs was medium, not large and I was wrong. My sister ordered the exact same in a large and had it quickly shipped and fit the dog perfectly and is so much better than a cone. my friend's dog could not eat or drink water with that cone and it was really bothering me. I will be donating my medium to a vet.
Our pup had surgery behind ear and this collar worked out perfect. She actually looked forward to putting it on as her head always had a pillow around it. Large and velcro works great with adjustment. Pup is an ESS about 50 lbs.
