Ideal to keep dogs busy
These types of chew are great! Low in fat, much longer lasting than pigs ears, pretty much odour free. They are safe to give to puppies and a must in my opinion when teaching them to associate good things with being left alone. Also great to be given when they are out and about (tube, coffee shop, bus, etc).
I couldn't recommend them enough.
And these come in a great bag containing 10 ears.
