Ok my pup (nearly 9 month old) has always been VERY itchy since the day I have had him. I took him off wagg and put him on applaws but this turned out badly as he always had the runs. But I did notice the itching lessen to an extent. So I put him on coconut oil. He is on a tablespoon a day atm and he weighes 25kg. This past month we have been painting and me not knowing that paint is damaging didn't no to keep him away till it dried. He was sick the next day every time we painted. But we did not put it down to that. We were using gloss and oil based paints :yikes:. Since stopping painting he has not been sick once! But I have however noticed a large rash pop up under his armpits, belly, itchy/red ears, groin area, and thighs. So I started rubbing coconut oil into him every day for the past 6 days and took him to the vets who has put him on piriton 4mg 3x a day to see if that helps. The next is an elimination diet. Well atm he is currently eating 3 things, a tablespoon of coconut oil, a tablespoon of diatomaceous earth and his kibble (anything from 350 to 450g) of skinners duck and rice a day and that is all. He has been eating only this for 2 weeks now. Tomorrow I am going to cut the coconut oil and DE out of his diet and stop rubbing him down with it to see if he is allergic to them. The only 3 things he is eating then is rice, duck and oats. If I have already taken the allergen away (in his tinned tripe loafs he was eating 2 weeks ago) how long would it take for the rash to go? The coconut oil helped to an extent but to me it looks like it is getting worse to me. Meaning the rash seems to be traveling down his legs. It is not infected, mites or ringworm. The rash are raised red bumbs that last about 4 days get crusty and drop off and then more pop up it appears to replace them. He has not been exposed to any chemicals for at least a week. I see no real pattern to it. I want to no weather dermacton would be helpful? Being as coconut oil doesn't seem to be helping? My main questions are Would dermacton be worth a shot? Should I switch to another kibble or stick with the duck and rice for another month? If I did go onto an elimination diet like the vet wants I would rather put him on a raw version. Any suggestions with this idea? I am becoming frustrated with this and so is he! He has one of those puffed up collars on to stop him scratching but he can still scratch his armpits. EDIT : As a side note, there is no issue at all with his stools . Regular as clockwork and firm. He goes about 4 times a day. He can go off his food slightly sometimes. Such as he may miss breakfast but he is eating 450g a day sometimes! He is lethargic sometimes too. He is always chewing his feet too. How long does it take for an allergen to get out of the system.
