Removed a dog tick, saw yellow stuff. What is it and what next?

A small amount of localized swelling and redness is a normal inflammatory reaction after tick removal. However, if the swelling and redness persists then you should have your vet take a look at it. You could clean the area with a wound wash and then apply a topical OTC antibiotic cream to the area. Make sure to use a good flea and tick prevention, NexGard, Bravecto, Credelio. Also, talk to your vet about vaccinating for Lyme disease is she isn't vaccinated. Monitor for any abnormal signs and talk your vet about yearly testing for tick borne diseases and heartworms.

Keep the area clean and dry. You can use a diluted Betadine or chlorhexidine (Hibiclens) solution to clean the area daily. Tick bites frequently result in a red, raised area (tick bite granuloma) after the tick drops off or is removed. The good news is that they resolve on their own within a few weeks. Resume Iggy's tick prevention and perform tick checks after being outdoors. You can have him tested for tick borne diseases in 6-8 weeks. https://www.petcoach.co/article/how-to-check-your-pet-for-fleas-and-ticks/ https://www.petcoach.co/article/what-to-do-if-you-spot-a-tick-on-your-pet-or-in-your-home/

It looks like the tick came out in one piece. When a tick bites, the saliva can cause a localized reaction leading to a firm granuloma. This should resolve on it's own over the next few weeks. In the meantime, consider an oral or topical preventative.

A tick bite typically leaves a "granuloma." This is a reaction to the tick's saliva. It should resolve on its own in a a few days to a few weeks. Monitor for signs of infection, lameness, lethargy, swollen or painful joints or fever. Use a [tick preventive](https://www.petco.com/shop/en/petcostore/category/dog/dog-and-puppy-flea-and-tick) such as FrontLine, K9 Advantix, Bravecto, NexGard or a Seresto collar. Always check for [ticks on your dog](https://www.petcoach.co/article/6-places-ticks-hide-on-dogs) upon returning home for outdoors.

Hello! It's difficult to tell for sure, but what I think I'm seeing in the photo is a nipple towards the upper left aspect of the photo, and an oval yellowish area below - I'm guessing that's where you believe the tick was removed? It is very common for dogs to get a small hard scab where a tick was removed, and as long as that scab is not red, inflamed, and has no discharge, it typically resolves on its own. Dogs do not get the stereotypical "bulls-eye" lesion that we watch for in humans to indicate Lyme disease exposure. However, if the lesion in question is that yellowish oval area, that would not be a normal response to a tick bite, and I would have that checked out by a vet. Your vet will be able to look at the lump and determine how concerned they are, and they will likely want to take a small sample with a needle to look at the cells in the microscope (cytology) to determine what is causing the lump. Additionally, if there is concerned about tick exposure, they can test for exposure to the tickborne diseases such as Lyme disease. I hope this helps!

A tick must be attached and actively feeding for at least 24 hours before the Lyme organism can be transmitted. If the tick was not engorged, it has not yet fed. Monitor for lameness, lethargy, painful joints, fever or loss of appetite. You can present the tick to your vet for identification if you still have it. Consider a topical preventative, collar or oral preventative to prevent fleas and ticks. Discuss options with your veterinarian.

Most of the time ticks will leave behind an area of irritation. As long as it is not bothering Jack, I would just keep an eye on it. If you are not on oral tick / flea prevention, I would strongly recommend putting Jack on something as a monthly preventive. If it begins to look infected, then I would recommend having a veterinarian take a look at it so that the most appropriate diagnostic and treatment recommendations can be made.
