Great product

I think this is a very good product. I have a big furry dog who weighs over 100 pounds. When she stretches out on the floor or stands up on her hind legs she is over 6 feet long, in other words she has a lot of body to cover. I just squeeze it between her shoulder blades and she pretty much stops itching for a good month. I will buy it again and again.

works great

I have used Frontline for years and not had any problems. I tried an off-brand and the smell was so bad, I gave the rest away. So, I was hesitant to try Onguard, but it looked to use the same ingradients as Frontline and was no where near as expensive. I tried it and it worked great. I have used it now through all seasons and had no problems at all with fleas or ticks.

Does Not Seem to Work

Bought this flea treatment for our two large dogs. Applied the product as directed. After about two weeks our dogs are still scratching and have fleas. We used Frontline Plus in the past. We tried this product because of the price. Frontline usually kept the fleas off for the month. This doesn’t seem to be working.

Bellatrix is ECSTATIC

I have a very large Rottweiler and 2 large mix breed dogs. The ROTTWEILER( Bellatrix) is extremely allergic to bug bites. Loses all of her fur in the summer. scratches and bites herself incessantly! At the end of summer last year we started using this product and it seemed to help but we were thinking maybe because it’s the end of the season. We continued with the product and still as of today she looks gorgeous with all her fur and minimal scratching! I love this product and so grateful to have found it ! She’s a happy dog this summer!

Works Quickly for Fleas!

Two of my six dogs are highly allergic to fleas. Last month, their former flea protection simply stopped working. In Florida that's common. These fleas thrive on challenges. Came across this while shopping around for an affordable alternative. The package contains six tubes for six months or six dogs. By the next day, they had calmed down and scratching was far less. Skin immediately began to rebound once the fleas were gone. A couple of weeks out and they are still calm and flealess. I'll be purchasing again.

Didn't work for a whole month and didn't protect well

This product worked well for about 3 days then I noticed some fleas on my boy but not many but within 2 weeks of application he is infested again and now I can't put more on him for 2 weeks. I want my money back to be honest.

Crappy meds.

None of my order helped my animals. All still have fleas bad, have dug and scratched themself bare. I can send the remainder back to you and get a refund or you can send something better, if not this is my last order thru chewy.

No More Explosive Diarrhea!

Bernie’s is absolutely amazing! We were back and forth to the vet for three months straight for our lab mix pup. We went to the vet to test him multiple times for worms, but the results kept coming back negative. After three months of back and forth visits to the vet, we eventually opted to pay for the vet’s overpriced prescription wet and dry dog food because we couldn’t bare to let our puppy (and ourselves) continue to suffer. Finally, my boyfriend came across a YouTube video reviewing Bernie’s probiotics and we felt like we had nothing lose so we gave it a try. & Thank God we did! Our puppy’s bowel movements are back to normal, the pup no longer struggles while using the bathroom and we’re no longer smearing poo stains throughout our apartment complex. Thank God for Bernie.

On Gard flea and tick topical

Decent quality product for a much lower price! Kind of a generic, no reactions in our pets.

Good Product

This is a good product. Seems to work just as well as Frontline Plus. Good value and doesn’t leave a nasty residue on her coat by the next day.
