Thanks for visiting Petco Pet Education Center, formerly Petcoach. Considering how far this appeared and the glistening appearance of this swelling, this appears to be a possible engorged tick. I recommend confirming that suspicion by looking really close for where it comes into contact with the skin to see if you can visualize rhebtick legs. You may have to pull up on the body of the tick a little to see clearly. Then proceed to remove this tick using tweezers or a tick removal kit from your local pet store. There are videos on YouTube that demonstrate how to remove ticks successfully. You want to make sure you grab it close to the skin so that you remove the entire tick head along with the body. Do no place any oils or any chemicals on the tick or this will only agitate it. If you don’t feel comfortable removing it yourself, then take Taco in to your vet for removal. Then discuss with your vet about after care and possible prophylactic treatment with antibiotics to cover any potential tick borne diseases. There is only a slight chance this is a mass, at which point a vet visit is recommended to get samples from it to determine what kind of mass it is and how we should proceed treating it. I hope this helps and best of luck with your pet Taco moving forward. Take care.
