Tick or mole?

Hi vets, Does anyone have any insight as to whether this looks like a tick or a mole on my dog? It's so hard to tell. It's not moving at all when we manipulate it. We tried to hold a hydrogen peroxide soaked cloth over it to see if it would encourage it to retract if it is a tick, and there was no change. Any ideas how to tell if it's a tick or not? Thank you!

Hello!   Ticks are attached only at the pointy end of the oval;  you can slide a peice of paper between the tick's body and the skin; literally they hang on only by the mouthparts at one end.  Lumps are usually more 'attached' than this.
