This bowl is so great when traveling with your dogs. It doesn't tip over and it has a rim all the way around the top to keep the water from spilling out while you're driving.

Pros: Keeps water from spilling all over the place.

Cons: Not the most durable.

This is a great watering dish, my dog can not submerse her head to drink. No wet spots and puddles on the floor from spilled water!

Pros: no spill

Cons: none

My grandpa has this bowl for his cocker. Her ears would get soaked every time she would drink. Not anymore.

Pros: keeps ears clean

Cons: ?

My parents have these in their RV, and they use them all the time. They have two dogs that go on a lot of road trips with them, and these bowls mean that the dogs can get a drink of water anytime without having to wait until their people stop for gas. Even though the water may slush around as your vehiccle turns and stops, the no-spill feature keeps the water in the bowl. Never let your dog (or cat) go thirsty again while on a drive!

Pros: Doesn't spill while driving

Cons: None

Another great concept that would only be enhanced if it were offered in stainless steel rather than plastic (the plastic retains bacteria, etc, that can cause allergies to many animals)

Pros: none

Cons: none
