I agree with what the other people say,
Buana is allergic to one kind of ingredient in some (cheap) kind of kibble.
The ingredient that some use to make it dry.
It's a sort of ingredient they like to use because it's cheap and easy to use.
Example Royal Canine, Pedigree, Bonzo and the cheap samples what you buy in the grocery he can't stand. But Farm Food, Hills, and lots of other kibble, he doesn't mind.
When he was a pup (that's when he got kibble), he had trouble with mosquito's but last year he had much mosquito bites and no trouble.
We know now, after a short test he is only allergic to one sort of ingredient.
I won't mind breeding with him, he has much quality's and did all the health tests thats were all with good results.
When a dog has good quality's but much allergy's in bad conditions I won't breed with that dog.
Allergy is a bad thing for owners and their dogs.
The way to the result of what they really allergic for are sometimes so long and not really cheap.
When I worked at the vet, we had at least one case of allergic reaction with a dog a week.. They first had to recover from their reaction (mostly with injections etc) and then they had to come back a few times to see what's the thing he's allergic for..
(test with al kind of possible allergy's injections on their skin, putting them on high hypoallergetic food or BARF when that don't change OR give a reaction, owners have to change their cleaning material at home, buy all new blanckets and toys etc etc)
Big problem with those tests are the owners, they try to give the hypoallergetic food to find out if it is the food, but forget they can't have anything else (no leaves, no sticks, no human food no snacks)
We once had a dog, that was allergic to new fleece blancets…
After all, not a big problem... but a very high bill with the vet..
(the owners, removed every blancket and toys.. but it was the fleece blanckets that were on the owners bed..)
That's one of the reasons I won't breed with a "high" allergic dog, the way to the results are so frustrating... for the dog AND the owner..
