> if this is the collar that I am thinking of, a friend told me it isnt good if what you are trying to stop the dog getting at is at the rear of the dog.
I like the comfy collar but you are right, they're only really good for neck, shoulder, abdomen type wounds, anything further back than the tummy or further down the front legs than the shoulder and the dogs can reach them - or at least most moderately athletic dogs can :-)
I've never had a dog that liked, or even put up with, the lampshade type so it's a case of simply covering the wounds and watching them like a hawk to stop them licking, this seems to be the best option :-)
