I think you brought up some really good points in your review. And I'm glad you pointed people to the FB page.
Wouldn't be good for dogs with cervical neck problems and dogs that have trouble swallowing from laryngeal paralysis or megaesophagus, for example. Also, the fact that he can't get the sizing right is a major problem both safety and health-wise. I guess he never tried the new design on his own dog to see if it even fit before running to the post office???? He was in too big a hurry to "fix" his mistakes.
I felt really bad for Sally's one dog, who obviously hated the thing. I'm sure Sally's dogs are pretty patient, but this was more than he could stand. I think most Newfs are pretty darn tolerant of silly costumes and other things we make them do and wear, so this was a surprise to me.
And the debris under the mouth parts was amazing. I didn't expect that either. That would surely cause irritation or discomfort for the poor dog, not to mention being continually wet if he got a drink.
Plus, the "instruction manual" (my description) is a complete joke. There are no instructions. I'll bet that was printed on the spot. With no thought. It didn't say how long to use it or have any disclaimers of any kind. Just to put in on when friends come over so they won't be offended. WHA!!! My friends ARE my friends because they accept me, my house, my car, and my dogs. But, if anyone of them had a problem, I would be happy to agree to alternative meeting places. Otherwise I would un-friend them pretty quickly.
The insert directed you to his slobberstopper.com website which has NO instruction video that I could find. The only other instructional one, on You Tube, just shows a kid putting one on the dog. No other instructions. Another one of them says to put it on and forget it. Maybe he should invent a telepathy machine so we can read his mind. There are so many confusing and contradictory statements, that I'm astounded! It's like handing a 3 year old a box of matches and saying have fun, don't get hurt. Actually, that says MORE than his instructions. If I was going to invent a product for the general public and send prototypes to people to test in their homes, I would certainly give them all the written instructions I could so they would have a successful trial with no error.
If I had anything else to add it would be that a little child might grab the "nice doggy" by this thing and get hung up in it right next to the dogs teeth, or snap the elastic on the dogs nose, and I am sure it would breed bacteria. Not a good combo.
You made a valid point that everyone will pet your dogs even if wearing this mask. I propose that a child would not be able to distinguish a mask from a muzzle and may think that all doggies wearing similar items were nice and pet-able.
