A pirep. I've had Mutt Muffs for 10 years. One set when my dog was a pup and a lager pair shortly later as she grew. The second set has 9+ years on them and are beginning to show some wear on the velcro strap. Having read comments about 4 Paws I ordered a set and now have them in hand. Well? I prefer the Mutt Muffs. The comments that 4 Paws are superior in hearing protection are unjustified. Mutt Muffs are built better. Mutt Muffs have a better chin strap. Mutt Muffs are easier to adjust to the head size. I can't find a single thing that's better with these 4 Paws muffs. If anyone needs a set on mediums I'll take 75% of the new price and I'll pay shipping. I'm buying another set of Mutt Muffs!
