After taking my dog out for a walk today I noticed a small white lump behind her ear (not sure how long shes had it, may be a coincidence?) I’m unsure whether it is a tick or not as I didn’t realise that they could be that colour. I’m unsure if its a skin tag or a tick? I’ve tried to have a look however shes not letting me go too near to her ear and won’t stop fidgeting. Any help?
