FAQ
I would like to perform a heating / cooling program where the temperature ramps from one set point to another over time. Are the PolyScience 20 Liter Stainless Steel Open Bath Systems capable of this?
That depends on the controller used. Only the Advanced Programmable controller can be programmed to perform ramps.
It is possible to have the circulation on without any temperature control being on?
No. If the circulation is on, then a temperature setting must be selected.

Extremely hard and durable
Color: Blue
These are very hard , but my puppy lives them and my large dog can't tear them up, so that is a huge plus.

Large breed approved
Color: Blue
these incredible aggressive chew toys – they've seriously been a game-changer for my pups! I know it's a bit late, but better late than never, right?
I've got a couple of power chewers at home, a Rottweiler and a Labrador, and anyone with big dogs knows the struggle of finding toys that actually last. These bad boys have been in constant rotation for over a year now, and I'm genuinely impressed by their resilience. They're incredibly tough!
Funnily enough, we originally had three, but now we're down to just one. The others aren't broken, though – I'm pretty sure my dogs just loved them so much they've hidden them away in some secret stash, as they tend to do with their favorite treasures!
Beyond just being durable, these toys have been a massive help with their training. They’re fantastic for redirecting all that enthusiastic chewing away from my furniture and shoes, which, let's be honest, is a huge win for any pet parent!
Considering how long they've held up to some serious chomping, the price point is absolutely spot on. You definitely get great value for your money.watch your toe they are heavy.
If you've got a dog that's a champion chewer, you absolutely need to try these out. They're a lifesaver!

Durable chew toy.
Color: Blue
My dog loves these. She chews on them a lot. She seems to like the different shapes. She is part Pit and an aggressive chewer. These chew toys last a long time. And I love the three pack so if we lose one, we always have a spare.

Decent durability for the price
Color: Blue
Bought a bunch of these for a dog shelter and have to say - decent for the price of you have aggressive chewers. All of the toys are still going 6+ months later, even with the strongest jawed pitty mix. Does get torn up at the ends but can easily be sanded down for a longer lasting toy, unlike some other hard toys with material not meant for sanding. The antler and ring seem to be favorites. The antler even has a divot so you can put soft treats in it or peanut butter and freeze it for a more interactive experience. Some came with a strong beef/liver smell but not overwhelming or off-putting. They are hefty without being too heavy, less likely to damage floors. Overall a good purchase
