Background & Aim:Increasing the tendency in families for taking care of pets makes people pay more attention to their disease especially the common ones. In recent years the tendency to use of herbal drugs has increased in animals. Herbal drugs are plants that one or some of their members have effective. We supposed that the Elaeagnus angustifolia(oleaster) powder has the plantagel. Therefore, the aim of this study is to compare the oleaster powder herbal compounds and plantagel as anti-diarrhea in dogs. Experimental: This study was done on 12 male dogs collar (3 quadri groups) with the similar approximate weight and similar age in veterinary clinic of Islamic azad university of Shahrekord branch. Sana flower herbal syrup was used to cause the diarrhea in all 3 groups. They received 15 mg/kg every 12 hours and all groups were suffering from diarrhea. Three groups were studied including testifier group without remedy, the first care group that received 5 mg/kg of oleaster and the second care group that received the plantagel powder every day and during this period of time the whole index related to diarrhea were exanimate whether on aspect of clinical or mortal factors. Results: By looking at the mortal indices, it was observed that the percentage of hematocrit in plantagel and oleaster groups in comparison with testifier group in recovery time was significantly different (P>0.05), that shows the recovery of mortal hematocrit index. Also the percentage of neutrophils in oleastergroup with testifier and plantagel groups was observed a meaningful difference which is reducethat is a sample of meaningful increase in comparison with other groups (P>0.05). Also by sampling from excrement, the numbers of the bacteria showed a meaningful difference in oleaster and plantagel group in comparison with testifier group (P>0.05). Recommended applications/ industries: The use of oleaster powder as dose and time dependent causes reducing the duration of diarrhea because of the prehensile materials in oleaster. پرونده مقاله
