It's difficult to give these a full review because it's winter now and therefore impossible for me to judge just how well they're working in terms of saving my grass.However, as I've now given these to my dog a number of times, I can judge them on several other dimensions.I've used quite a few different products like this over the years. Some are better than others in terms of smell/taste, effectiveness, efficiency (as in how much is needed per day), and my dog's reaction to the chew.In terms of smell, these are mild and non-offensive. I've actually had chews in the past that were kind of stinky to the point where I didn't really like handling them. Relatedly, my dog really likes the taste of these. He's more than happy to gobble these up when they're offered, which makes them easy to use. He's had no negative stomach reaction to these chews since we started them either. And, he has a bit of a sensitive stomach, so that's certainly a good indication of quality ingredients.My dog is around 60 lbs so he falls squarely into the 2/day category. This is pretty standard from what I've seen. So, he gets one at breakfast and one at dinner time. There are 100 chews in the jar so this is 50 days worth of product. At the current asking price, that comes to $0.60 per day. That's pretty good. It's not the best in terms of cost, but it's not the worst, either. If they end up working well in terms of protecting our lawn, it's a perfectly reasonable price.So, from my experience so far, I have nothing but positives about these chews. I'm actually going to pause using them for a while and pick up again in the Spring to really test them out fully. If they don't do a good job of protecting our lawn, I'll revisit this review and adjust it accordingly.
