Does my dog have a tick? What is this?

[GoldenRetriever]

Hello, I'm looking for some help.  I'm wondering if my dog has a tick under her skin. It doesn't seem to be very painful to the touch for her. We cut the hair away from the area and applied polysporin, and the images we're taken after we did so. There is some puss and blood over the area and it is scabed in some areas. We havn't found any insects around the spot. Could someone please provide some insight. She is female golden retriever age 3. We spend a lot of time in the woods, lakes, and, rivers. Thank you

Hello GoldenRetriever,

I just read your comments. I would take your three year old golden retriever
to your regular vet.  Let the vet examine your dog. You said their is puss.
That usually means an infection. I think I read somewhere that its not
advisable to use what call " people ointment" like polysporin on your dog.
Infections needs antibiotics and only antibiotics availabe from a vet.
Good luck in finding out what's going on. Eve :)

Hi there , very clever of you to include the photos.  
I'm no expert , but the wound is clearly infected and your dog needs antibiotics.   If it were a tick it wouldn't be infected , and you would notice behavioural changes like lethargy and lack of appetite.  
Try bathing the area with warm water to clean it and apply antiseptic cream if you have some.
