"Our standard poodle has always struggled with stinky and cruddy ears, even after grooming. After trying these probiotics for 30 days, we noticed a significant decrease in the crud and smell!

"As a dedicated dog parent, I was on the lookout for something to keep my pup healthy. I decided to try the Wag Probiotic Supplement Chews and was pleasantly surprised!

Plus, the quality ingredients and resealable packaging are fantastic!"

Highly recommend for small dogs with sensitive stomachs!"

I can't remember the price, but it's worth it!"

"I've been giving this to my dogs for a while now, and they absolutely love it! They really enjoy the taste, and it works wonders! I highly recommend it!"

"I have three fur babies, and they absolutely love this product. After dinner, they let me know they're ready for Meh-meh (medicine), and it seems more like a treat. It has significantly reduced their grass-eating habits, which is impressive considering we live on a farm. I’m grateful for the scheduled deliveries and highly recommend this product!"

"With my three smaller dogs, they enjoy these probiotics without realizing they're helping them stay healthy. They no longer itch or scratch, and they have great coats without dander. Their digestive issues have vanished too. I also supplement with omega-3 oil and milk thistle weekly to support their liver health."

"My dogs can be picky, especially when it comes to probiotics, but these Advanced Probiotics are a game-changer! They actually love them, and I’m no longer forced to trick them into taking their probiotics. I’m so relieved to finally find something that works!"

"I had hopes for these chews, but my tiny dog wouldn't eat them. I had to chop them up due to their size, which was a bit inconvenient, but I still tried giving them to her."

"I’ve been giving this to my fur babies for quite a while, and I believe it has helped them because they have well-formed stools in the litter box. They needed the probiotics after receiving antibiotics from neighborhood cat fights. I started with a small sprinkle, and I suspect those who had adverse reactions may have given their pets too much too soon."

"This is the first probiotic I've tried for my cats, and I chose it because it has more pre and probiotic strains than others at similar prices. The supplement has no added flavorings or meat proteins, and the results have been noticeable. However, I did find the container to be only half full, which was a bit surprising."

"We’ve been using this product for several years now, and I definitely see the difference in my dog’s stomach and skin. Our 12.5-year-old dog loves this probiotic powder sprinkled on his food, and he feels much better overall!"
