Chewy Is Ace Yet Again

With a new Westie pup joining our family in Jan., he was immediately checked over, by our always reliable/trustworthy/highly valued Vet. At the age appropriate

With a new Westie pup joining our family in Jan., he was immediately checked over, by our always reliable/trustworthy/highly valued Vet. At the age appropriate dates, he received all of his necessary shots, but in these times, protection from harmful, disease bearing fleas and ticks, is always a required, invaluable addition, to his health regimen. As with “All-things-dog,” Chewy, yet again, offered the correct dosage needed for our new fur baby, at a significantly lower price. Upon our Vet’s recommendation for Credilio, to stave off, harmful fleas and ticks, Chewy’s uber customer-friendly staff, happily assisted us in arranging, ongoing delivery of this important medicinal supplement. We have found, no other pet retail outlet, whom comes close to offering this medication at such a low cost.

Credelio the Great!

I've used a few different things, natural and over the counter flea/tick meds, ointments, shampoos and always would still find 1 or 2 fleas...... then my veterinarian

I've used a few different things, natural and over the counter flea/tick meds, ointments, shampoos and always would still find 1 or 2 fleas...... then my veterinarian told me about Credelio and this tablet is amazing! From the very first couple of "hours" I used it 3 years ago I've never seen another flea or anything on my boy, JAX. I love the fact that I can break the tablet up as well and sprinkle it over his food, usually with shredded chicken breast. He is 5 years old now and thriving..... no scratching or biting his fur and skin. I have recommended this product to many people.

Only the safest and quality med for my 4- legged kids:)

Dogs seem to like the taste, ate it without other food. wrapping around to hide it. Vet recommended. And from what I’ve read by others and scientific reports. No

Dogs seem to like the taste, ate it without other food. wrapping around to hide it. Vet recommended. And from what I’ve read by others and scientific reports. No bad side effects and most consumers are glad their pet is on it. They’re my 4- legged kids! I’m protective and want no harm to come to them. I want them healthy and I’ll do my part. Hopefully the manufacture makes a quality and safe product. :)

I have 3 older dogs that have never had fleas until we moved into a new house. They have always been on a flea preventative but apparently they became immune. I tried more expensive flea meds, vacuumed frequently, used dog, house and yard spays. I even tried putting salt on the carpet as I read this would help kills fleas as well. My dogs would seem clear for about a day after bathing with flea shampoo but then they quickly returned. Since we moved too far from our previous vet, I found one closer and asked for help. I cannot tell you how wonderful it is to have had the fleas gone what seemed like immediately. One of my dogs was allergic to the fleas and was constantly itching, I was getting bit and itching frequently too. It was horrible! Credelio is a God send. It rescued us from that terrible nightmare. I am so glad Chewy sells it for a lower price than what I can get from my vet. Saving money is a great thing and with 3 dogs...it's necessary!

Wonder what the margins are on this product?

You are paying a lot of money to essentially poison your pet. On other pet meds, i have saved big $$ by using Good Rx. But you cant buy Flea, Tick, Heartworm

You are paying a lot of money to essentially poison your pet. On other pet meds, i have saved big $$ by using Good Rx. But you cant buy Flea, Tick, Heartworm meds using Good Rx. I have heard that you can buy this same stuff through companies in Australia for a fraction of of the price in the US. I an going to check to see if that is true. Why does a company that supposedly loves pets want to make it so much more expensive to own a pet? Sorry Chewy it sure does loom that way

I will only use this product!!!

I recently moved to a high tick infested area. Needless to say, I could not walk my dog without her getting at least 1 tick. I let her out in our back yard since she was on Advantage II and I found 12 ticks that night. Our Veterinarian recommend the Seresto collar, which didn’t fully work. The collar is supposed to repel ticks completely and I would find them dead but attached. My Veterinarian then recommend to try the chewing one and gave me Credelio since it works faster than most for ticks. I love this. This has been a life savor. I do find ticks on her but I find them attached and dead (not engorged). We are at peace knowing that they will not get her sick. I will highly recommend.

We had nearly given up. Felt so defeated. Tried front line, Adams, advantix, seresto. Drops. Collars. Sprays. Nothing was working. We used this for our 3 dogs. This is the end of our first month using it. This is my go to from now on. Definitely buying again. Btw, I didn't even buy this on chewy. I got it through my vet while we were already there last month. But it worked so well that I had to make a review for it on here to help out any poor souls that are struggling like we did. I have found 2-3 fleas but I picked them off and they were alive but couldn't even jump. Just kicking around a little before dying.

Fantastic Product that WORKS

I bought the Seresto flea collar based on reviews. This product did not work! My dog continued to have a BAD flea problem despite having the collar on. I flea combed him daily and found tons of fleas. I wrote the company twice with no reply. After 2 weeks of no improvement and no contact from Seresto, I gave up and asked my Vet about oral med for my 17 year old terrier mix. He recommended Credelio. It is amazing. Fleas are GONE. Two thumbs way up!! Photo was taken one and two weeks with Seresto collar.

A good Alternative

I have used another flea medication for years...suddenly I am unable to find the size appropriate for my dog. My dog is older and has some seizure issues, so I did

I have used another flea medication for years...suddenly I am unable to find the size appropriate for my dog. My dog is older and has some seizure issues, so I did a lot of research, including talking directly to the product manufacturer, to find a new product that seemed safe for her and effective against fleas. I wanted a "simple" product that only addressed fleas...not heartworms, etc. etc. She has had no adverse reactions of any kind to Credelio. I'm grateful to have found this substitute product.

First time user

I got this prescription when my dog recently became over run with fleas! I had some friends recommend it. 2-3 days after giving her this, she stopped scratching

I got this prescription when my dog recently became over run with fleas! I had some friends recommend it. 2-3 days after giving her this, she stopped scratching and I haven’t found a flea anywhere in our home! Highly recommend for anyone who has had a recent flea infestation! Also, chewy.com contacted our vets office and got the prescription, which saved me a lot of driving, as a busy mom of 3 that is a HUGE help! Will definitely be getting all of my dogs needs through chewy from now on!
