My vet always prescribed PREDNISONE for itching. Poppy had 2 rounds of that - it worked a miracle - but I don't think it's worth the possible long term effects. Now we're trying Medrol . I never heard of it . I'm hoping this works to control her itching with less side effects. Have you ever used it ? My vet is so wonderful ... he took a whole half an hour with me to explain allergies & answer any questions I had. His office calls are only $25 ..... He's a saint . I'm just wondering if this brought relief to your dog if you've used it .
