Hi, just hoping someone can help, my dog has a spot on her ear which I’ve just noticed tonight. It’s about 5mm and looks like a pimple but has a black head on it. It’s not hot or swollen and she’s not bothered by it normally but when I was touching it to try and check it out it it was obviously causing her pain for me to touch it. I’m not sure if it’s a tick but I don’t know if this is what ticks on dogs usually look like? Usually I would call the vet but they don’t open until Monday and I’m just wondering what this could be in the meantime. She’s otherwise well in herself. She’s a golden retriever, she 5 and usually in good health. Not sure if it’s just a regular pimple and I’m just worrying about it for nothing! If anyone can help or offer any advice I would be really grateful x
