Great product

This is excellent for keeping your dog's (or cat's) ears nice and clean (no infections). I have Old English Sheepdogs, but many breeds have the same issues with their ears. The dogs don't seem to mind it too much, I just gently rug below their ear for a minute after squirting some directly down the ear canal that I position by sliding a small finder a little way down. The 12 ounce bottles are a really great deal and will last a long time, I find that using once a week they no longer get otitis externa requiring topical steroids and antibiotics or antifungal treatment.

This stuff is amazing

One of my dogs used to get ear infections so I started cleaning their ears (and my kitty’s) weekly. Since I started using this - NO ear infections. And when it’s ear cleaning time, even my kitty comes running to get his cleaned. LOL

In the almost 7 years I've had my shih tzu rescue Charlie, she has had ear infections at least 8 times a year (probably more). About 15 months ago my vet recommended trying this every other day and she has not had a single ear infection since. I put it on a cotton ball and wipe the ear and that works perfectly.

This product saved us from a vet visit. We used it just a day or two after we noticed fluid in the ears and it worked great. Ears are now dry and clean. We will continue to use it to maintain healthy ears!

Trizultra Keto Flush for Dogs

Getting the Trizultra Keto earwash for Dogs for my Mattie was vital in helping her to finally recover from a bad ear yeast infection for quite a while. Order was easily placed & delivery prompt. Chewy service to pets is EXCELLENT!

Stinky ears & Yeast ears

This product was RX through my vet 2 yrs ago. When I ran out I emailed Chewy to ask if they carried this product. I was so happy they did and ordered a larger bottle then at the vet’s office 2 yrs ago, and it was 1/2 the cost. Now my fur babies no longer have stinky itchy ears. And I just love communicating with the Chewy Pharmacy Staff, they are so compassionate and knowledgeable. Ty Chewy

Good product

I use this weekly for both of my dogs. I use it with a cotton ball to gently wipe the ear and squeeze the liquid into the ear. They both have had ear infections in the past and this has kept them from getting more infections and away from costly vet bills.

No more nasty ears!

Finally found a product that helps my old guys ears! With age my poor old man has recurrent fungal and bacterial ear infections, with this flush it's the first time he hasn't needed medications in over a month. Thank you!!!

Helps clean ears

My dog has trouble with dirty and yeasty ears at times and this stuff does good at cleaning them out. I put it on a paper towel and wipe out his ears thought, otherwise he shakes his head and this stuff goes everywhere before I have a chance to clean them. Doesn't seem to cause any irritation.
