Shes 8 months old, white and deaf. The last couple of days we noticed she had a dark patch (not like her black fur spots that shes developing) om the top of her head. she had sap stuck to her bum once and it kind of looked like this but not sticky or anything. Just dirty looking. today we have noticed that it's more like a bald patch. its literally right on the top of her head between her ears. Are staffys prone to any type of skin problems? I'll take her to the vets in the week but just wondered what anyone thinks it may be. shes been flead and her injections are up to date but hasn't been speyed yet fwiw.
