We walk our 2 dogs twice a day and go through 4 or more bags daily, it’s nice to not having to depend on plastic shopping bagsMy only gripe is that they tend to tear when pulled out of the dog waste station holder if the user is too aggressive or uses only one hand.I always buy these for my dogs poop and I love it!These were bought for people to use in an RV Park. The perforations are too difficult for people in a hurry (or whatever their reason was} to tear one off. They would pull out 3 or 4, get one and let the others blow in the wind. Perforations just need to go a little deeper. Otherwise, good product. A little small to put hand in to turn the bag inside out.wish there were some individual dispenser available with it.Good value. Durable.We have a 35 pound mixed breed and this is suitable for this sized dog or smaller.I was really hopeful that these bags would be big and strong enough to do the job. I'm finding that, unless you have ladies size hands, they are just too small for men. Once the poo is picked up, it's very difficult to fold it over without getting poo on the outside of the bag. I have used about thirty bags now and one of them, my finger came through a split in the bag. Not fun.The old saying is true: You get what you pay for. I tried to save some money on the usual bags I get, which are the Poopy Pouch Tie-Handle Pet Waste Bags. There is a world of difference between them. Now all I have to do is make it through 2000 bags. I can't just throw them out.UPDATE: I just happen to use one of my neighbor's bags, and they are great! It turns out that they are the Amazon Basics bags that are advertised at 13 x 9, but are absolutely wider than these bags that are advertised 16 x 9 ( x7, whatever that means). I'm not sure how you can have a bag that's sealed at the end have three dimensions. If you want a good bag that is cheaper than these (but better), buy the Amazon Basics bags at this link... https://amzn.to/2m4t0Z5 . They are $14.99 for 900 (which is $45 for 2700).At my current office, we have a nice little patio area outside. Our street gets a lot of foot traffic and boy did we have a lot of dogs using our pretty grass out front as their dumping grounds -no pun intended hehe. I was able to order a doggy doo-doo station and we use these backs all the time. We go through a box or two a month and sometimes even more if the weather is nice out. They are black bags and a very good material as they do not tear and are not cheap whatsoever! I highly recommend this to anyone who is a dog owner!
