Disappointed
Color: S6-muti-color
These were great for about 20 minutes then they stopped squeaking...we have 2 left that I have saved but the other 4 do not squeak anymore...disappointed as my dog loves to squeak things...would not buy these again...My dog is only an 8lb dog too...but he can still play with the balls without the squeak...

Great Value for a ball my dog loves!
Color: S6-muti-color
I wish these ball were in the subscription program! My dog gets sooo excited by the new ball, but her interest in things lasts for a few days. She kills the squeak within 11minutes, but the squeaker stays in place rather than becoming a chocking or swallow hazard, and she still loves to chew it. Next, we must throw the ball approximately 723 times the first day, possibly 496 times on day 2, and just 3- 4 on day 3, at which point she will chase the ball before hollering "it's over here if you need it," while she checks on the chipmunk den. We currently have 17 of these balls in our yard (because we have given several leftovers to a less discriminating doodle next door). These balls hold up really well, get her extremely active for the first couple of days, and are a much cheaper than doggie daycare (after an active morning with a new ball, she is happy to chew on it and sleep much of the day). I always have these on hand!

Pieces chewed off
Color: white & green
My Aussiedoodle loves it. I throw it down the hallway, it bounces crazy, and he chases it. The only complaint is that he can't chew much of the ball part. So now I have to have it put away and brought out for special playtime.

Love these spoons!
Material Type: Plastic
Have ordered these spoons a couple times over the past few years. They really are sturdy and great quality I just hate that since the pandemic they went from $13 for a box of 1000 spoons to $27 but like everything else around us, the price has risen astronomically! Anywho, we’ve used them for Thanksgiving, Christmas and everything in between. My daughter uses them every night to scoop out cat food like someone else mentions. We have two cats and we don’t want to dirty up a spoon ever night for their nightly feeding when we divide a can of kitty food between them. I’ve used the spoons to mix resin, paints among other crafts and they’ve always held up without bending. Truly their worth the price but man it hurts the pocket when everything we buy right now has doubled to tripled in price now! (Even that dad-limb cat food! Lol) But if you can swing the cost I can promise you it’s worth it. They hold up well for hot soups and those big scoops of banana pudding like mine that is heavy! I’ve bought their forks once and they are just as good but we go through spoons so much more around my house.

Love these plastic spoons. Bonus - need no washing!
Material Type: Plastic
Excellent product, these spoons aren’t small for teaspoons like other brands. They’re strong enough for all types of food and never bend it break. Also, the price is right for so many spoons. I always by this brand.
