<s>[INST] We have a 10-yr old yellow lab, female, that the dr. thinks may have a bacterial infection in her intestine (per bloodwork just done) and will put her on a broad-spectrum antibiotic and probiotic--is this contagious to another dog in the household(mini-schnauzer) and/or humans since we have to wipe her botton 4-5times a day? [/INST] Bacterial infection can be transmitted easily via a Pectoral route. If the stools come in contact with a food item and that foodstuff is accidentally ingested, It can easily cause intestinal infection in other household persons also. So take care to clean her up after every stool and dispose the stool properly. Also take care to keep other persons clean. Get your nails cut as under nails are a good site for dirt and spores and cyst collection. Thanks and regards. </s>
