Chuckit medium rebound balls
Size: Medium
My 8 month old German shepherd dog loves these balls. They are easy to throw, they bounce great, they are very chewable! She keeps one in her mouth most of the time. It satisfies her need to chew and she does not chew other things. She drops it in the water and lets the hole fill up and drinks that way. The only problem that has caused is suction in her mouth and difficulty in dislodging it for her. However, she would be lost without it!

These are definitely indestructible
Size: Medium
Both of my dogs can destroy a ball in a matter of minutes if I let them play with them (supervised) as is. Well not with these balls. They are the ONLY ones I have found that are 100% indestructible. Please only let your dogs play with these as a toy when supervised though. They go really far when throwing them, so both dogs get a good amount of running and exercise with these. I also bought these because they have the hole in the middle of the ball which is very important in the event that a dog gets one stuck at the back of their throat. This allows them to breath unlike those without this hold. It's an unlikely event, but as dog owners, we all need to be aware of this and educate ourselves on what to do if this SHOULD happen. This isn't a scare tactic, nor a reflection of this particular brand, it can happen with any type of ball. My two dogs are about 45ish lbs and the size is perfect for them, I don't want anything smaller than this. They love them. There is no annoying squeak. Really easy to wash after use. Some balls take forever to get the slimy saliva off, but these don't.

Best Card in My Wallet!
Having this card from Prime/ Sync has made things so much easier ! I order something & then go to cart & pay with my Prime card, nothing more. I don’t need to worry about theft or further actions or delays. It’s a done deal & I have more time added to make an additional purchase if I need to in case I forget something. I love this card 💞. So easy, I buy more here cause it’s faster, safer, & all in one easy step & Amazon has just about everything there is so why not ? Best card in my wallet !!!

2026 it has saved me
I never wanted a store card only! When I first applied I was bummed that I only got the store card and I thought about canceling it. BUT A lot has changed this year for sure. New grandparents, grocery being so EXPENSIVE and everything in our house as far as electronics needed to be replaced. Very easy to apply for, love the fact that you can apply without getting a hit on your credit and if you want to accept the offer then do so and if you decide that it’s not enough credit then you can decline the offer and no hit to your credit. I will say this, this was the lowest card that I was offered but I chose to get it anyway and within a month I had already received a credit line increase. I also took a trip out of the country and was able to order stuff and have it delivered with no problems. Every time I use it I get cash back and am able to use that on my next order. This is my weekly card for groceries. I definitely can’t wait until it upgrades to the visa, I would definitely get more use out of it. For those who are Amazon shoppers, it’s well worth it. So far so good, Good Choice.
