NexGard seems to make our puppy itch. We have only had him 2 weeks, he does not have fleas. We gave him his monthly pill as instructed by the Vet and he is itching now. Is that ok or should we switch brands for next month? 18 pound spaniel-terrier mix. About 4 months old. Pet's info: Dog | Mixed Breed Medium (23 - 60lb) | Male | neutered | 4 months and 7 days old | 18 lbs

Puppy Itching After NexGard: Is This Normal or Switch Brands?

I gave my dog fle & tick Nexgard about 5 hrs ago for the 1st time and ever since shes been scratching and biting herself non stop. Shes miserable. Is this a side effect? What can i do to help

It has been known to cause local skin irritation, but the itching could mean that it is working if she had fleas on her. I would see if there is a number on the package to call for advice. If the itching continues into tomorrow or if she's actually injuring herself with the scratching or starts having other symptoms such as lethargy, loss of appetite, vomiting, etc., get her seen by your vet as soon as possible.

My pet has been itching to the point where she is bleeding in her armpits and paws. She is on Nexguard medication but still appears to have flea bites. There was about a 1 week period where she was off of the medication--so I'm wondering if that has

This is probably due to an allergy, although it could also be infection or mites. First of all, in order to rule out skin parasites, you will need to treat with a high quality flea treatment (advocate or advantage), then ask the vet to perform a skin scrape - this might reveal an infection or a mite infestation. If all of those came back negative, the next step is to treat the allergy symptomatically and try to discover the cause of the allergy. Three main type of allergies are usually affecting pets: food allergies, flea and parasite related ones and environmental type (allergens coming from trees, pollens, dust etc etc). Some medications can be given by the vet in order to repair any possible skin lesions (like steroids and antibiotics). Please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further.

Jax has also had red bumpy areas around his back legs. He has been scratching at the rash looking section for a day now and I am 99% sure that it is fleas. Should I get him and next guard chew and if I do will that stop the itching within the next

I am very sorry to hear about Jax's itching. Nexgard is a great product for fleas (I use it on my own dog) but it isn't going to make the itching stop immediately as it doesn't affect inflammation in the skin. The itching if it is due to fleas is due to flea bites that have occurred (the flea doesn't have to still be on the dog). Some dogs are especially sensitive to flea bites and it can make them very itchy. Often these dogs benefit from a short course of steroids to really stop the inflammation/itching. I would call your vet to find out if they feel you should bring Jax in. They may decide to see him to prescribe medication, or they may be able to tell you an over the counter antihistamine you can try. You can also try a soothing shampoo/creme rinse such as something with oatmeal or if your vet sells shampoos I like the Episoothe product, and a fatty acid supplement which can decrease inflammation in the skin, but often a few days of steroids will stop the problem much more q

Is NexGard really bad for dogs? What should we do in case he shows bad symptoms? We gave Voldemort one yesterday. After about 12 hours, the ticks were on the tiled floor, they looked like beans. We were thinking it was so effective. His body was cove

He will still scratch, as the ticks injected an anesthetic into the skin and he may be reacting to that. I would not worry about this at the moment, as this will go away within a few days. Since you are finding a lot of dead or fallen off ticks, The Nexguard is obviously working. It takes a few days to kill off the ticks. Sometimes they just dry out while hanging on and then they will eventually fall off.

Thanks for using Boop by Petco! This is possibly due to allergies. It could actually still be flea allergy dermatitis if the fleas are still not under control. It really comes down to figuring out what is causing his allergies so that they can be treated or the specific allergen avoided. There are many things that can cause allergies though in most cases they can be broken down into 3 big categories: flea, food and environmental allergies. Allergies are usually worked up in a stepwise fashion starting with flea allergies as this is the easiest and cheapest to take care of. If not on a flea preventative, then it would be a good idea to get started on one. If already on one then it would be a good idea to change to something else (there are many new products out in the market). If not improved in 1-3 months then it is time to move on and check for food allergies by switching to a novel diet (new protein and new carbohydrate). If that does not seem to be the issue then you are left

Hi, thanks for using Boop by Petco! I think the topicals sometimes cause tingling or burning. My dog didn’t like the advantix spot on. I really like the new oral flea/tick medications, monthly nexgard or simparica or every 3 month Bravecto. I hope this helps!

Thanks for using Boop by Petco! This is possibly due to allergies. He is still scratching possibly because the allergic component has not been discovered and treated yet. It really comes down to figuring out what is causing his allergies so that they can be treated or the specific allergen avoided. A secondary infection is likely and also needs to be addressed. There are medications such as steroids and one named Apoquel which may help with the itch.

Sorry to hear about all of Jazz's issues. Dermatologic issues can be very frustrating and take a long time to resolve unfortunately. In terms of the steroid shots, if those are not working there are definitely other medications available that can assist with the symptoms. The first two the come to mind are Apoquel, which is a daily medication that is given orally, and the second is Cytopoint, a once monthly injectable biologic. I have had fantastic success, far greater than with steroids, fighting against severely itchy dogs. The itchiness associated with both fleas and food allergy should be addressed with both of these medications. In terms of switching to a different flea medication, I would switch if you feel you have been finding fleas. If not, then I see no reason to change to something else. Nexgard is typically a really good choice, which is part of the reason it is so expensive. As for the dietary changes, these trials can be very long and often require repetition with
