Sponge Filter with Bio TumblerSponge Filter Included Fluidized media is the gold standard for aquarium filtration for two reasons: massive biological surface area and zero maintenance. While ceramic rings lava rocks clog with waste and lose most of their efficiency within weeks, moving bed technology is 100% self cleaning. The tumbling K1 media continuously sheds dead biofilm, maintaining maximum ammonia processing power for heavy bioload predator tankswith zero maintenance

Could be more durable.
Color: A-Navy
It’s not as durable as I’d hoped. I’ve had to mend it. It’s cute, though, and my dog likes it. He’s an Aussie, so not great bite strength.

Cute but disappointing
Color: C-Navy+Oak, Color: C-Navy+Oak
One of my dogs love these however they are far from indestructible. Two days after giving the teddy to him, the tail of the teddy is off and there is a rip by one of the arms. They are very cute teddies but not for heavy chewers as they will only last a few days.

Nothing is indestructible
Color: D-Purple
Adorable. Looks just like the photo. My 15# JRT loves it! however the tail and one ear were gone in a matter of minutes. It’s his toy so I’m just monitoring his time with it as it’s his favorite 😍

Our Pit Bull’s Favorite Toy!
Color: A-Navy, Color: A-Navy
We absolutely love this MAXBECK bear toy! We’ve ordered it 4 times over the last 8 months because our senior pit bull is obsessed with his “babies.” He always has one close to him and even cuddles with them. The material is very sturdy and holds up amazingly well even with rough play. My dog’s favorite part is the squeaker. What I love most is that even after he finally tears into it, the rope built inside becomes a whole second toy for him and keeps the fun going. If you have a heavy chewer who destroys toys quickly, this one is definitely worth trying!

Not indestructible
Color: C-Navy+Oak, Color: C-Navy+Oak
I assume it is probably hard to create an indestructible product, but my puppy had it apart in no time.
