I found this in my dogs hair whilst grooming theres no way it had been there long, but is very strange?! Its about the size of a small nut and would fit on the end of your pinky, Seems to have 8 legs and 3 feeler things.. Picture taken with it turned upside down, moves extremely slow, any identification would be great. I think it must have been picked up in the garden or on a walk. Thanks
