My dogs love these!

I have three very large dogs who absolutely love these treats. They are very picky because they’re very spoiled! But yes, they love these!

Good value
Pattern Name: Ring, Size: 0.42 Ounce (Pack of 10)
This is a new treat for our sweet girl and she loves it! She’s a small dog so I break them in two and it’s just enough.

My Shih Tzu goes crazy for these!!!
Pattern Name: Ring, Size: 0.42 Ounce (Pack of 4)
My guy’s favorite treat. He sticks his nose on the bag and can barely wait for me to get it open. Doesn’t upset his digestion. Have ordered multiple times and will continue to do so.
