Frequently Asked Questions
At what age is my child ready for a belt-positioning booster like the Tanza?
The Tanza is intended for children who have outgrown their forward-facing harnessed car seat and weigh between 18 and 45 kg (40–100 lbs) while measuring 110 to 145 cm (43–57 in) tall. Most children reach this stage around age four to five, but always check your current car seat's outgrown limits first.
Can I install the Tanza without the UAS connectors?
The Tanza is designed to be used with its rigid UAS connectors for a secure fit. Refer to the product manual for your specific vehicle compatibility and installation guidance.
Is the Tanza allowed on airplanes?
Belt-positioning boosters rely on the vehicle's lap-and-shoulder belt and are generally not certified for aircraft use. Check airline policies before travelling.

Not for a strong destroyer
Golden retriever destroyed this quickly but I’m starting to think he can destroy all things.

So many squeakers!
Color: Squeaker Matz Gator, Size: X Large (Pack of 1)
I have 3 golden retrievers. They love this toy. While the head came off because they played tug-o-war with it, the rest has held up mostly for 5-6 months. At this point sometimes a squeaker will pop out. There are so many squeakers in this toy! However, they still use it for tug-o-war, I am surprised it has lasted this long. There is only stuffing in the head.

Cute, durable toy.
Color: Squeaker Matz Gator, Size: X Large (Pack of 1)
It's about as durable as you can expect a stuffed animal to be. I have two new puppies who are still teething and they love these things. I got the Kyjen sheep mat version (it's a square shape, rather than the two rows of squeakers) for the little girl. Both dogs sleep with it in their crate and we take them on trips with us. I've gone so far as to open up the toy and replace the broken squeakers (costs about 5$ for 30 large squeakers).
The rest of the toy is fine. Our german shepherd puppy absolutely loves the rattle that's located in the head of the gator as well. The rattle also helps initially getting the dog engaged with chewing on the toy rather than your clothing or furniture. Then they discover the squeakers and it's endless entertainment and a good distraction for your dogs.
I haven't had any problems with the thin, decorative material that's represent the teeth, claws and back fins. It's a slightly thicker felt that's soft and flimsy. Honestly, I'm not worried about it. Even if they were to eventually chew these off, they're not a choking hazard. Our little guy has thrown up solid pieces of kibble that are larger and harder than this. Seriously now, common.
The eyes are sewn into the head, so there's no risk of pulling them off and swallowing.
I toss these in the washer on a gentle cycle to clean off the slobber and dirt about once every couple weeks and the squeakers are fine, though they sometimes have to dry out to be 100% functional again. It never takes long.
Overall, I love the amount of squeakers just due to the breaking problem with have with single squeaker toys. Once they break, the dog loses interest. Which is also a nice way to train the dogs the difference between the non-squeaking kids toys. The dogs absolutely love this toy and wont sleep without it. When the fabric eventually wears out (not even a slight issue after a few months), I'll be buying another one.

Great Toy, HUGE, small dog loves,
Color: Squeaker Matz Gator, Size: X Large (Pack of 1)
For the price this is my favorite toy! My 4 lb Chihuahua LOVES this thing. He is smaller than it by a long shot, yet he loves to parade this around, showing how big he is and can handle this huge GATOR. LOL.
Friends come up to the porch, and he runs back to grab his GATOR to bring it up for them to see.
Only thing with these toys - for my dog - we have several of these he loves - he cannot make them squeak. He jumps on them, chews on them, but just doesn't have the power. That being said, think about it, he loves the things, I mean LOVES. Sleeps with them, parades them out, fights with them when he's alone, has a great time - .... Evidently, it's me - I MISS THE SQUEAK! I watch him, and root for him, and every now and then (rare), I hear he got a squeak. Still, he doesn't care! So.... interactive time! I go out and play with him and Mr. GATOR, and I make it squeak, and we all have EXTRA fun.
Note, my little guy is what they call an EXTREMELY AGGRESSIVE CHEWER. He chews in his sleep (kidding). He's really a tough chewer. He however, uses these more for wrestling, and attacking, and carrying around and sleeping on, etc. So none of ours have tears in them, though he does attack and chew all of it -
I think these products are super wonderful, and I have to buy several more, like the hide-a-toy ones (beehive, squirrel, etc.) because I know the quality, I know my Chihuahua loves them to pieces - while he hasn't actually been able to render them in pieces! Win-win for us.
You decide what your dog is like. Mine has his snoopy blanket and a huge victory in his mind over this large GATOR - his friend all day long.
