Excellent Treats for Small to Medium Dogs!
Flavor Name: Peanut Butter, Size: 2.19 Pound (Pack of 1)
I’ve purchased the Purina Busy Bone, Long Lasting Small/Medium Breed Adult Dog Chews, Peanut Butter Flavor - 10 ct. Pouch several times over the last few months, and they’ve become a staple in our dog’s treat routine! Our three dogs absolutely love them. The peanut butter flavor seems to be a huge hit, and I appreciate that these treats are made in USA facilities—I feel more confident in the quality and safety. They’re just the right size for small to medium breeds, and they last long enough to keep our pups occupied for a while. Plus, they don’t have that overpowering smell some chews do, and they don’t leave a mess behind, which is a big plus in my book. Overall, these are a high-quality, tasty, and reliable treat that keeps our dogs happy and busy. Highly recommend for any dog owner looking for a long-lasting chew that’s both delicious and made with care.

Mr. Diggy approves two paws up
Flavor Name: Peanut Butter, Size: 5.25 Pound (Pack of 1), Flavor Name: Peanut Butter, Size: 5.25 Pound (Pack of 1)
These just arrived earlier today, and Mr. Diggy just had one a little while ago. Well, it was gone fast. He is 60 pounds and 14 years old and loves his treats so I make sure I have good ones for him because he can’t have that many. What a nice strong bone and you could smell the peanut butter. He was so excited he took it and went to lay down. He only does that with special things. I feed my dog and cats, Purina pro and I can see since they’ve been eating it that it agrees with them and makes their coats, soft and shiny besides. That’s why I bought these because they are made by Purina and there’s no rawhide I bought the larger bone and I’m glad I did. It’s a good size for him. They call him a medium sized dog, but they never tried to pick him up lol I am going to check now and see what other flavors they have although peanut butter is his favorite Try them I think your dog will like them. Mr. Diggy gives two paws up for these.

smells good, teething puppy loves gnawing on it as I hold it.
Flavor Name: Peanut Butter, Size: 2.19 Pound (Pack of 1)
I normally don't do treats like this, but my mom had purchased a small pack for my dogs. I was reticent to try it, but with a new puppy I was looking for something for little miss alligator teeth to chomp on that isn't my fingers. It worked out so well (I held it while she gnawed) that I purchased a big pack. While not meant for puppies, it has been working well for her to have something to grind her teeth on. Currently 10 weeks old, 20 lbs (a yellow lab) with super razor sharp teeth that is all about chomping on everything in her path. These slow her down for several minutes. She is blissed out as she works on it. Have to say, these arent super long lasting even with a tiny-ish puppy. But at least the price is good. We have had the original (pretty much no odor) and these peanut butter ones which even smell good to me! I may consider these again. Be mindful of calories! 343 calories a piece. Be mindful of their serving suggestion based on size of dog. This isnt meant to be a meal, and not meant for daily consumption. More of the rare treat style. Ingredients Rice, vegetable glycerin, wheat flour, water, brewers dried yeast, chicken by-product meal, hydrogenated corn syrup, sugar, corn germ meal, beef tallow preserved with mixed-tocopherols, pork, natural and artificial peanut butter flavor, partially hydrogenated vegetable oil, wheat gluten, phosphoric acid, salt, sorbic acid (a preservative), gelatin, calcium propionate (a preservative), BHA (a preservative), BHT (a preservative), calcium carbonate, citric acid.
