Working in the veterinary field I'm pretty particular with what I give my dogs. I want it to be safe, have no added chemicals or choking/teeth hazards, and keep three high energy dogs (two pit mixes and a border collie mix) entertained and QUIET for at least a short while. If it doesn't cost an arm and a leg, and helps clean their teeth too, that's a bonus. So here are my thoughts after going through half of the bag.Pros:• THEY ARE BIG. reading reviews this was what really sold me, and it's true, these are much larger than what you usually see, and they keep my dogs (even my most leisurely chewer) busy for much longer than most treats• No smell - at least none that was detectable to me when I shoved a dead pigs ear almost right up my nose :))) even when they chew I haven't smelled a thing.• Not messy. No tiny pieces break off, and unless you have a drooly dog there's no evidence to be seen, but that isn't the products fault• No chemical additives, all natural. Many treats sold on Amazon and online make dogs sick, cause diseases and have owners deep in vet bills and grief, so always read reviews! These ones are straight from the pig and not chemically enhanced.• Safer than rawhides, and not hard enough to break any teeth. Also, even if your dog does manage to swallow a large piece, these will break down instead of do continuing to absorb moisture and bloat in your dog's stomach, but even my 60lb dog who loves to swallow anything and everything only managed to gnaw smaller pieces off of these. I'd say these would be good for any sized dog• The gang LOVES them. stuffed Kong with bacon cheese spray who?tennis ball who? chicken who? well...they may prefer the chicken, but these are their favorite dog treats. It's 5 stars from them.They also say these promote dental health, and while that may be true to a very small extent, these, nor any other treat will replace the need for brushing or getting their doggie dentals, but hey, even a little help is better than nothing.Cons (only one!)• They're a little expensive...though I've seen even pricier for sale on Amazon that are probably not half as big as these. Granted that I can go to my local pet supply shop and get pig ears for $1 a piece, these ones are significantly larger and take my pups significantly longer to finish, so for me it's worth it to pay almost $2 per ear for a little bit longer of peace and quiet. I still hope that they drop the price, or make a deal on the 25ct bag, I'd buy them forever.I'll buy these again, and in the future plan to only adopt smaller dogs so that when I get these it'll take them even longer to finish it. For now my 30, 40, and 60lb dogs will continue to enjoy these and gobble them up in 15 minutes, and I will cross my fingers and hope that pigs grow even larger so that I might even have more quiet time someday.
