If you want to try something natural, here are some suggestions:
You could try is Slippery Elm (purchased from a local health food store not GNC) given an hour or so before eating will coat and calm his stomach and prepare it for food. This is used short term.
Have you considered that chicken or flax seed in kibbles could be causing your dogs problem? It does with many. Read the labels carefully to make sure there isn't chicken or chicken fat somewhere in the list. My boy is sensitive to flax seed!
Also, be careful with treats and the ingredients they contain. Choose high quality (non grain
) or make your own.
This is the recipe my holistic vet suggests: Boneless, skinless de-fatted chicken breast or turkey breast, or Ground Round Steak, boiled, grease rinsed off, shredded and cooled.. Mix 50/50 (or 1:1) with canned pureed PLAIN pumpkin. Again, adjust amount per day fed for your size dog, and divide into 3 or 4 smaller meals. No kibble during this time. Keep them on this for a few days then very slowly add a small amount of kibble per day, increasing as you watch for loose stool. Cut back kibble to previous amount if stool loosens up....this is called "bowel tolerance". Keep at that rate for a day or so, then increase kibble again.
Many on this blog have given their dogs Kocci Free for Giardia/Coccideia (all herbals) with great success! I'm wondering if you needed another round of it or giving a longer period of time?
For myself and another member here, I found that adding a Homeopathic called "Bowl Pathogen Nosode" (Aids in enhancement of immune response to typical bowel pathogens.)
and a good quality MSM really works well if it is a tough case.
Bowel Pathogen Nosode: http://www.amazon.com/Bowel-Pathogen-Nosode-Professional-Formulas/dp/B00E4QUPRE/ref=sr_1_1?ie=UTF8&qid=1434401576&sr=8-1&keywords=bowel+pathogen+nosode This is given separately from the Kocci Free and the MSM. Homeopathic's are "given in a clean mouth" meaning no food or water 30 minutes before or after dosing.
MSM (an organic sulphur) makes the bowel "a very unfriendly place for parasites". There are very different grades of msm. I feel after researching, this one is the best! My husband and I take it too for our joints! Read about the certifications here and on Bergstrom's other pages: http://www.bergstromnutrition.com/our-company/certifications
. On that page is a company called Kala who distributes it. They are great! I get a 10# container. I give it every day as our property is full of wild life. This can be sprinkled on to his food.
Feel free to pm me if you decide to go this route and need help.
Hope your boy gets better soon!
