Could my dog's new hard lumps on his rib and chest be tick fever?

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 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.

This looks like a bacterial skin infection. It is not very likely to be related to the tick issue. Sometimes a medicated shampoo bath helps clear this up but other times oral antibiotics are needed. If this is not gotten better in the next 1 to 2 days I would contact your veterinarian to discuss antibiotics for Opie.

What you describe can definitely be a tick bite or a small tumor. Toto should be seen by a vet to determine the cause of the lump you are seeing, as it may also be an infection. If the lump is caused by a tick bite, Toto should be tested for Lyme disease and other tick-borne illnesses. A tumor can be removed and sent off as a biopsy or a smaller sample can be taken with a thin needle. I recommend having him seen soon, especially if the area is getting larger or you believe it is causing some discomfort. In the meantime, you can get him an E-collar or "cone" to prevent scratching and further trauma.

I am sorry to hear of your loss but without a full post mortem exam there is no way of knowing what contributed to such a severe condition. Tumours in the legs generally do not resolve within 5days and the severe, progressive anemia would indicate a possible bone marrow condition or autoimmune disease which may possibly have been triggered by ticks or an internal tumour

Sometimes thed skin reacts to the tick bite with an overproduction of connective tissue fibers. This usually feels like a hard little knot. It is more a beauty issue than a medical issue. This is not something you have to worry about as long as it does not grow in size or changes color or shape. It will likely get smaller over the years or maybe stay the same.

While hard to say without seeing her in person, this does not have the appearance of a tick and looks more like a small skin growth. Ticks are usually dark in color, black/brown/maroon and once full of blood can have a pale grey appearance.
