This is the 4th of these that I have purchased. The first 3 had the same problem, the plastic stopper strap tears away from the stopper. We will see how the 4th one lasts.I bought one of these on our trip in California. This was a game changer. Now there are many varieties of this kind for larger dogs. You really should always carry some kind off water for your dog while out walking or traveling in your car or etc. I had to a new one on Amazon because I have a particular dog who only likes to drink from drinking cup. I had the old one for a long time that the enclosure finally broke off. Excellent productI have two of these and have given it as a gift to my friends with pets. Its very convenient, hooks on to a belt or backpack, holds the perfect amount of water for a long walk or car ride, and the attached bowl is big enough for him to get into easily for a drink. When my dog is finished drinking, the remaining water flows easily back into the bottle. It is make of sturdy plastic. Every dog owner should have one.This is the perfect traveling water bowl. Simple and no mess! I bought this exact bowl at a farmers market in 2009 or 2010 and it’s still great. Bought this one now to keep in the car in case I forget one at home and I was shocked that they’re so hard to find! I’ll take good care and hope for another 11+ years.Love this water bottle, its the third one I have bought in the last 5 years, as now I have one for each of my cars. Its great for traveling, as I can let my dog drink from it and pour any left over water back into the bottle. It beats rolling down my window and throwing unused water from a cup out the window from a moving car. I bought the small size bottle as I have small dogs. The cap stays on tight and it never leaks.It’s great for summer and easy to carry.This makes 5 times that I purchased from this company. I recommend them toi every as it is helpful in the heat while strolling with our 14 year old Pug.I purchased this dog bowl and bottle because it was all one piece and I was tired of having to take the bottle apart and put water in the detachable bowl and make a mess every time and it was just bothersome. I ordered this product and have been really happy with it with the small exception that when you open the plug, which is attached, on the bottle and put water in the bowl the plug is kinda in your way. It is not enough to make me dislike the product though.
