Vented loops are commonly used in the marine toilet system and engine cooling system. The simple valve system incorporated in the top of the loop allows air to enter the line when not in use, yet effectively seals as water or other fluid passes through. Molded in Marelon, neither vent nor loop will corrode. The duckbill one way valve

Tall lost Tail
Simba went fishing for a good time, but it looks like the fish toy got hooked on destruction instead - gone in 20 minutes!

Nice toy, but maybe not so durable
This is our second one of these, which really speaks to how much my dog loves it… it’s cute and just the right size for my Vizsla. She absolutely loves playing with it… it’s chewable and has a nice squeaker, but I’m not so sure of its durability. Our first one lasted about a month, and this one just a couple of weeks. The stitching at the tip seems to give away first, then the find. Sadly, you gotta throw it away when you see the first signs of the stuffing.

Good quality for the price
More durable than others. We have an aggressive chewer so I know the squeaker will be destroyed eventually. The fact that it didn't get destroyed day 1 is a positive.

Go with tough rubber toys---you'll be ALOT happier!!!
This item isn't worth the thread used to make it. Only took my little puppy approx. 45 min. to gnaw the squeaker out!! The edging "tape" didn't last 1/2 that long. NOT good choice for tough teethers!!! I hand sewed damages---no help. For good toys---go with the KONG-type strength---REALLY TOUGH!!!
