So when I first saw this I thought it was a great idea but in practice, I'm not so convinced. You need to make sure the lid is on very tight or else you're going to end up with wet food. I learned that the hard way... My other complaint is that the water section is kind of small. You end up having to refill it pretty often. Especially if your dog is like mine where they don't really eat much when they're out but they drink a whole lot of water. It's certainly isn't a bad product though and serves its purpose pretty well. Just be careful with the lid!I really like the idea. I have the following issues, however:1) Bowl is way too small for any dog that isn't tiny. The bowl itself doesn't stay open well (which can be an issue when you pour water into it).2) Compartments are small as well. I understand this is a half and half sort of device, but honestly, water is more useful than having food, when going on hikes and outdoor trips. I don't know if there was a way to do a 75/25% split, but I think it would improve the usefulness of the cup.3) The caps for the lids close by pressure only and are not threaded on. This can be problematic when you are moving fast (i.e, running) as the caps can become loose or completely fall off.I've bought a lot of dog stuff, but this might just be the most useful item I've ever bought. I have 1 dog in training to be a therapy animal, and one in training to be a service animal. Needless to say, they're out of the house a lot. Lugging their water bowls and a water bottle around was a pain in the neck, not to mention kind of ridiculous when all they wanted was a sip of water. Some of the reviews say that unless you tighten the top really tight, it leaks. I haven't had this issue, but it's easy enough to get around. Just tighten the common cap as tight as you can and then use the individual compartment tops to refill the water and treats.I was really excited to see this kind of portable pet bottle. I bought it for my dog to use on our family mini road trip. It seemed really convenient to be able to carry food and water in the same container. However, this product did not last long for me at all! While waiting to pack up the van, my bags fell over from about 3 feet up from the street and the bottle dropped out and broke where the lid for the food was stored. I know it's plastic and not the same material as say, a hydroflask, but I was still disappointed as we didn't even start our trip yet. I endured the trip by just placing the bottle in a large ziplock bag and it ended up just leaking water in my purse. I wish the product used a stronger material or tweaked their design for the two separate closures. I hope others have a better result using it than I did--maybe I just had bad luck this time around.I love it I didn’t realize there is a food side I thought the top of the lid was just for food but it’s a water bottle split have one water one food!A neat concept, but the execution is a little off. The bowl doesn’t want to stay “open,” and the water leaks if the top is not on JUST right. Plus, any dog over about 30 pounds will have outgrown this bottle.Terrific for our walks, hiking with the dogs.This gadget is the bomb! I am about to travel 1,000 miles by Geryhound with my little service dog and this holds the perfect amount of water for the 24 hour trip, and more than enough food. What a great idea to attach the drinking cup.Great idea will be used loads, bigger than thoughtExcelente forma de salir de paseo muy practico yo lo uso en el cinturón y facilita mucho poder llevar tanto agua como alimentos en el mismo bote y la capacidad suficienteE' l'acquisto migliore che abbia mai fatto per il mio cane.In vacanza ci è stato di gran aiuto - non saprei come avrei fatto senza: le crocchette, l'acqua e la ciottola erano sempre con noi.La mattina preparavo tutto e potevo stare tranquilla per il mio cane tutto il giorno.Ora lo porto con noi al parco, sulla spiaggia, in macchina.Lo consiglierei a tutti che hanno un animale.J'ai fait cet achat pour le transporter de l'eau et de la nourriture pour mon chien en excursion, mais surtout pour mettre l'eau et la nourriture dans le petit bol. Je suis déçue du produit car le bol ne reste pas complètement ouvert, il se referme toujours.Worked well as I had hoped.
