We have a seven and a half year old Kelpie x and she's always had skin allergies. They don't seem to be related to any particular season as they are constant all year round, though sometimes they do get worse. On the advice of the vet, she's been on a grain free diet for several years now, but considering the allergy has persisted, I'm assuming it's not a wheat or grain based allergy.
She also takes allergy medication (prednisolone). But it doesn't seem to work, or perhaps she's become immune to it because she's been taking it so long. The vet just refills her prescription and gives us dosage advice but I'm starting to think we need to do something different because it's clearly not helping and she must be so irritated. Her skin is always red (normally in patches, though sometimes it's all over) and lately her fur has become patchy in areas and her scratching is pulling it out. She's had allergies her whole life, but lately it's just getting worse. She's always scratching or chewing at her fur/skin and I just want to make it better for her.
Is there anything I can do that will help? I'm in Perth if that makes a difference.
