I'm starting with diet you guys recommended. They told me that I should give about 135g of food daily, separated in 2 meals (morning and evening)....so it should last for little more than 3 weeks. I will inform you of results.
Btw, I was told by the guy in pet shop that Taste of The Wild foor is too strong for bichons.
Also, my Nero is not as white as he was as a puppy (I noticed that when he stands by some maltese)... he told me that Taste of The wild is the reason for that also.
Bichons are pink skinned dogs, can lead to skin issues. The color change could be due to chronic intolerance etc. When we first got the bichon years ago, he was so matted that the groomer had to take the fleece off to the skin - sheared him like a sheep. He was literally pink, looked like a little piglet.
As for taste of the wild too strong, I don't know what strong means - but best quality doesn't necessarily equate to best for your dog. Some foods are high in protein and carbs, usually meant for more energetic go go go breeds. Many hunting dogs get put on a higher carb diet for field trials.
Throughout your 3 week food trial, try to keep a daily log of when the dog eats and poops - and if you can, what the poop looks like, hard/soft/runny. Take note of any positives or negatives in the dog - if any appear. If it is a food intolerance, you should notice some difference by the end of 3 weeks.
4th day of diet...no changes. Even worse...I just came back from work and saw this on rear leg:
He had elizabethan collar, but he manages to grab rear legs over it, so there is no way I can prevent this. And now he bites this wound in front of me. No mather how much I yell at him, he cannot resist doing it.
I am really wandering what is happening with this dog. I am 99% sure that this has nothing to do with food. But let's wait and see...
If your dog is highly allergic to chicken then even though the chicken was hydrolized in the food it might have still been too much for his system. I know 2 dogs like that, chicken, no matter what form it's in, sets off major reactions in them. That might be what's going on and why the food did not work.
Have you considered home cooking for him for a month, doing that you'll know exactly what he's eating, and can par it down to just a couple of ingredients. I'd suggest something like 1/2 meat (make sure it's something he hasn't had like maybe pork) and 1/2 quinoa. I suggest the quinoa because it's novel, not a grain, and is considered a super food. If he does better you know for sure it's the food, if not then it's likely environmental.
I'm not sure if you knew or not, so I'll mention it, when doing a food trial it's important to only give the dog the trials food and nothing else, no chews, no treats. If you must give the dog treats make sure it's the same ingredients as the trial food. What a lot of people do is simply use the protein type (fish, chicken, pork, beef, etc) as the treat.
What I'd also do is wipe him down whenever he comes in from outside, especially his paws, legs and underbelly. That should help to cut down on any environmental allergies that he may have.
He could be highly allergic to fleas, I've seen flea allergies cause that type of reactions
If you really suspect environmental allergies an allergy test might be worth the money.
In the meantime, we went to new vet and he did thyroid test which was ok.
Then he checked his anal sacks and squeezed the smelliest fluid I have ever smelled. He said that it can be the reason for the problem, so we must monitor Nero's condition in next days. He also gave him dexamethasone injection and told me to give him dexamethasone tablets for 3-4 days. He told us that dog wont stop biting himself immediately, but he should in 2-3 days. And that exactly happened. Nero was able to sleep without elizabethan collar, which was equal to wonder to us.
But...when we stopped with dexamethasone tablets, he started to bite and scratch himself again.
During next 2 times we went to vet, anal sacks were almost clean, and we would repeat dexamethasone therapy....problems would stop as long as he takes them.
Vet then told us to switch to methylprednisolone (I dont know why), which had same results as dexamethasone.
And as conclusion...the vet said that Nero has atopic dermatitis which has no cure and that dog must be on drugs almost always.
Since Nero was not on drugs for 10 days and he started making wounds...vet said to give him 1mg of methylprednisolone per 1kg for 15 days. He wants to determine the lowest efficient amont of methylprednisolone that Nero can take.
Here's where he bites himself the most right now:
Any comments on this? Is there really no cure for atopic dermatitis?
