How long for Advantix II to dry? Can my dog go outside if still wet?

The medication will ideally dry for 12 hours. It's pretty close so likely the medication will work fine. Be checking Booker (especially around his tail and groin area) to be sure. Don't reapply medication with out a vet's ok. I hope this helps and please feel free to post any additional questions.

In most cases, it will dry in an hour or two. It is best to avoid contact with the area though until it has dried. You may notice a "greasy" spot at the site of application for a few days after. This is normal and will resolve.

Since a bath wets the skin significantly and also softens it, I suggest you wait a few hours until your dog is completely dry , ie has a dry hair coat as well as completely dry skin. Once the skin is dry there should be no problem with application of the tick and flea treatment.

I would not reapply the advantix until she is due. Getting wet once or twice shouldn't greatly affect the efficacy of the product. But if she is a water dog one of the oral flea and tick medications may be a better match for Tikka

He may have an adverse skin reaction to the Advantix. This happens sometime and should subside within a few days. You should really apply the spot-on onto the skin between the shoulder blades after parting the hair. The skin is less sensitive there (thicker), Should the spot where you applied it get raw, you need to have it examined by your veterinarian.

You are correct Stuart is showing signs of side effects from Advantix, which can last a bit. Once the product has been absorbed by the skin, you have to wait for the active ingredient to be eliminated from the body before the side effects stop. That's not to say that nothing can be done, and I do recommend taking him into the vet as he sounds uncomfortable. There may be medication the vet can prescribe to help with his itchiness. Best of luck, I hope this helps!

It's possible that the product is burning or that he can smell/feel the product on his skin. I don't recommend to re-apply the product and I suspect the application is not the problem. You may try using a hair brush and brushing the area of application. Do check the skin to make sure it's not red/scabbig. This will generally stop within 24 hours. Moving forward, I recommend to speak with your vet about an oral flea product like Simparica. I hope this helps.
