We have a 2 year old Chocolate lab (Josie) who has cushings disease. She is on Vetoryl tablets doing and is responding really well , but the vet tells us that her immune system is really low as she keeps picking up other illness's (at the moment she is being treated for ringworm). We have been trying some tablets called "Tasty Vits Canine Coat" but they don't seem to be doing much. Does anyone recommend any tablets that can boost the dogs immune system. Also does ringworm cause the dogs to itch as she constanlty keeps scratching which is causing her bald spots and red sore areas (mainly by her front legs). The scratching is why we took her to the vets for 6 months ago, and although they have diagnosed the cushings they cannot seem to stop her scratching. Has anyone else come across a similar problem??
