I'm about lost with it to be honest mate like now it is twice the size but you'd have to really squeeze it for a yelp from him im thinking more hes damaged it a week ago broke or ligament tendon damage and nothing to do with the hole a fortnight before
he will yelp at the bottom of the toe but not the nail bed and its not hot
Going to be rest I recon but ill pop.see greyhound vet in a few days
