Hi,
I have a herbal remedy from my herbal dog book that you may like to try. All the herbs can be bought very inexpensively from a health store in your town centre.
1. You can make a brew of dandelion (leaves and / or flowers); also, soak fenugreek seeds in warm water, 2 tablespoons to one cup or more, for 24 hrs, then give the liquid as a drink, and feed the seeds mixed into a cereal feed.
2. Give linseed tea, strong infusion; also apply the tea externally.
3. In severe cases, make suppositories from pulped, raw dock leaves and insert in the anus. Also apply diluted witch hazel.
Hope this helps
Karen
