The one I have is used for 3 cats. I have to refill it once a week. I am also not sure if the one i bought was 3.5 gallons. I think mine is smaller. I do however love the brand.

I think it was 3 gallons. I actually purchased it for a friend so I not positive. But it was really nice! Pretty big unless you have a lot of counter space.

I've never measured the capacity. I would estimate somewhere in the neighborhood of two quarts. The volume isn't really a problem since it fills as fast as an animal drink. Even my two thirsty Dachshunds don't really lower the water level appreciably when both are drinking at the same time.

I would advise not to fill it up all the way because it is so so large, but it is very easy. It is actually larger than the ones in the pet stores that you see, so it is a great deal! I have 2 large dogs and they drink all day and don't even drink half a bottle! All you have to do is attach the gray drinking piece to the top and then turn it over, then set it on the ground.

It is small, and holds about 2 cups. We fill both bowls with water. That work well for our Australlian Terrier

I love that water bottle and you will too. I have two African Ridge Backs and although they are not as large as your mastiff they are a sizable dog. The dog will smell the water and lick it and from there he will know where he can get water from. If you put it outside and I did, do not place in or near sun as the metal nozzle will be to hot for them to drink from.I have my bottle hanging from there dog run, I got it because I got tired of mess the water bowl caused. You will need to order the larger one as I found this a bit on the small size for a dog as large as mine, so I order two. If you ever had a hamster as a kid, It is basically a hamster watering system just on a much larger scale. I love that water bottle and you will too.

The larger bowl holds 9 1/2 cups water the slightly smaller bowl holds 7 1/2 cups of water. I use both for water and for my 75# dog and my 35# dog it lasts a couple days....I use both for water since I have two dogs. Depending on the size of kibble I would imagine the food would be about the same as the water..hope that helps.

The large bowl holds right at 2.5 cups of large-kibble dog food. Hope that helps!

I just checked and it holds 5 cups of my medium breed kibble. Hope that helps!

My two large german shepards like to drink at the same time. There is plenty of water for both.

I have 2 great danes a german shepard and a pit..All 4 eat out of these bowls...I have two of these sets one for food and the other for water. The bowls are huge! I'd say they hold about a gallon each.

I have a 55 lb. shepherd/husky mix and this bowl hold enough water for her to get a really good drink and then some. I also like that when you put water in, the bowl sits perfectly and does not have a big tip factor.

I have put 4 cups of dry food in but have never measured the water. It is larger than the food bowl. It lasts over a day with my 125 dog.

The drinking area is about 3" square. The water is fairly shallow so it would most likely be difficult for your dog to play too much.

My dogs are 60 and 70 pound dogs. They have no problems drinking from the bowl.

It's huge I dunno. I have never measured. I feed to cocker spaniels. Roughly maybe 12 cups?
