Kaiser and I have been working on a suspected allergy for awhile now, thought to be a contact allergy which really seemed to be grass.
Due to his skin getting sooo much worse back to holistic vet to get to the bottom of it. No dog park for a month. Trialled a few medications and ended up with Gastriplex one tablet twice a day, cut his raw food done to rabbit mix which contains heart and tripe for two weeks with freeze dried tripe and venison as treats, just started giving turkey necks and he will now stay on this for 6 weeks. Boy this has been hard for me as I have tried hard to give him a variety of raw and found it hard to give him so little. Big thing I did was no sprays fly, air freshener etc, bought a steam mop for floor and carpet as I would use a carpet freshener now and then, bought him cotton throws to sleep on and what I reckon was the thing that has helped him most is changed from Persil to a natural eco friendly no fragrance plant based washing liquid, saw results within a couple of days. So Leaky Gut leads to weakened resistance to toxins and how did it happen? well stupid me took Kaiser to my regular Vet for a cut on his paw( had a bad experience with my cat with a paw cut so wanted to be on top of this one) at about 6 or 7 months old and he was given antibiotics, then at 8 months he went in for his neuter/hernia repair so he would have been topped up with more antibiotics, giving him his road to gut flora imbalance and sensitivity. Also think that he started off with a sensitive tummy dealing with fatty foods. We have been back to the dog park and no problem with the grass, that makes me very happy as he loves it there. His skin is still sensitive but not inflamed it is still stained from his licking but am seeing parts that are turning a normal colour. So after 6 weeks I get to introduce another protein for a week and then another, slow and steady we go. Hope this helps some people dealing with allergies to realise an unhealthy gut can also lead to allergies that wouldn't usually happen if their pets gut is working properly and avoid antibiotics when you can and supplement with good gut bacteria if used. Hope this wasn't too boring and lot's of people already know this info, but this is our experience and we wanted to share.
Jolanda and Kaiser.
