Della is 14 months, and the problems appeared when she was 10 months old, at the same time as her "fake pregnancy" (I am Swedish and might not know all words correctly, sorry?). Also, I had spoiled her with a lot of different foods, so thanks to that mistake it is hard to see what caused the allergy.
She had a gastroscopy and that was how they discovered the chronic inflammation and the allergy. The vet said that maybe we wouldn't have noticed the inflammation unless she had also had the allergy, that the two of them together became too much. So what we are hoping for is to fight off the allergy, and that the inflammation would then be quite symptom free. ISPD and IBD was never mentioned. Basenjis are not so common in Sweden, but I will ask my vet about this. He is the only intestinal specialist we have in the whole Stockholm area.
She never vomits any food, "only" bile when the tummy is empty. So the nights have been the worst, even though I fed her her last meal very late she woke up and threw up after a few hours if I did not go up and feed her before. During the days I was able to avoid her throwing up thanks to giving her small portions every third hour. But she felt sick in between, and she did throw up as soon as I was 10 minutes late with a meal.
After starting with the cortison, she was first very tired and depressed. But the dose in the beginning was very high. Now she is eating a small dose, and she is like herself again - except for being a bit swollen and having a problem growing back hair on the area where they shaved her leg preparing for the gastroscopy, she is at least happy and playful, does not feel sick and sleep all night. Now I feed her four times a day, with the last meal given btw 10 and 11 at night.
The first thing I am hoping to do is to find out what she is allergic too. If anyone has any specific food to recommend, that has worked out for their Basenji, please let me know and I will discuss this with the vet too. The hyperallergenic food she gets now is based on soy (!) which I have heard from several of you is usually not good.
Thank you/Sofie
