Lightweight Leather Basket Muzzle Well-Ventilated for Walking, Training, Vet Visits and Transportation

My Irish Wolfhounds have a bad habit of eating acorns and hickory nuts which are toxic to dogs and cause them diarrhea. I have about 15 of these trees in my yard. I ordered one muzzle and it was so effective in preventing them from eating the nuts that I am ordering a 2nd one today.
