After one week my dog went to the vet with an intestinal blockage. Vet said that he sees this often with these chews. They are meant to be well chewed as the chews are very dense. If your dog doesn't take the time to really chew them (as most dogs don't), then it can end up getting stuck in their system.
I was hoping my dog would chew it, but he did not. He first buried it in a blanket in his dog house. When we gave it to him again, he made a pile of rocks outside and put it under them. When we gave it to him a 3rd time he took it back to the dog house again and buried it in his blanket again. He likes it enough to hide it, but so far after 2 hours it doesn't look like he will chew it. He is a spoiled dog and since he has a bad heart, we primarily feed him homemade dog food with no hormones or antibiotics...stuff that most people would love to eat. I didn't want to give it a totally bad review since my dog is not typical.
Better than what the reviews said and I prayed they had no worms in them. My bag came worm free and was happy enough with that. Still I can't say I would buy again I took a chance but the reviews were bad and I was hoping to get lucky and hoping that the company made changes to the process to rid themselves of the work issue.
I can only give 3 stars because I don't know if this is a one time thing. I have had back luck with duck treats on Amazon the 2nd time around so I can't say for sure.
These are hardly "Petite". I cut them into two pieces for my little 6lb Maltese. I've given them away when I discovered that these are made with grain which should NOT be fed to a Maltese. Greenies do come Grain-Free; this particular bag is NOT.
