I need some suggestions for our 4 1/2 year old Healer by the name of Tate. She is 35 lbs. and fit as a fiddle. Last summer she started to have loose stools at around this same time and after multiple visits to the vet, nothing was concluded. Below are the steps we have taken. 1. Went on a chicken and rice diet for WAY to long last summer. 2. Eventually changed food to a more fiber enriched diet with the Iams Health Weight. 3. After some time, the loose stool issue went away, but it was after the summer and a ton of chicken and rice. 4. We have not run a blood work test because are stupidly expensive and after several visits we well dragged that out and finally decided not to. We thought we solved the problem with the switch in food but yet again the loose stools are back - same time as last year. I strongly believe this has something to do with this time of year / heat / allergies. BTW our backyard is majority synthetic turf and no plants that she is getting into. Same for inside the house, no plants or strange food she is getting into. We are at a loss. Could it be allergies? The heat effecting her digestive system somehow? Have any other healer owners experienced this with theirs?
