So I've had my puppy Harlow for two months now, shes 16 weeks old. For about the past 4-6 weeks it seems she's had a very sensitive stomach, anything out of her eating routine such as even one small training treat, different water, change in any of the small amount of wet food I give with her dry causes diarrhea/soft stool. Ice cubes she loves so I treat those as her treats and she acts as such. Whenever she would get a two day diarrhea episode I would feed her rice with her kibble and sometimes some cut up boiled chicken breast. It still seems like every 2-3 days she has solid but soft stool with some mucus on it and her next poop an hour-2 later will be regularly solid with some blood and then maybe solid with blood for a day and then back to normal and then back to soft stool with mucus two days later and on and on. She's acting like herself all the time, never lethargic, always wants to play and chew like normal. She constantly tries to eat leaves, grass, pieces of sticks, etc etc and I do a pretty good job and removing every little thing she picks up and attempts to swallow but surely sometimes she swallows those type of things. She is fully house trained, sleeps all night without whining in her crate etc. So all in all she is a great dog. This seems like a minor problem maybe from the outside looking in but when its every 2-3 days for weeks on end it gets old and makes me wonder if its something that needs checked out or if it will start to cease as she gets older. When this first started she had pure diarrhea in her crate and vomited as well at around 10 weeks of age which prompted a vet visit. The vet wanted to do all the rounds of tests, x-rays, blood work and charge $600+. At the advice of our breeder we only opted for the exam and a prescription of meds which cleared her up with no issues for a few weeks and thats when we noticed giving her anything outside of her regular diet caused these issues. My neighbor walks/feeds her everyday midday and may be sneaking her a treat here and there so that could be my constant issue as to her stool/stomach issue. Any thoughts, tips, hints, and suggestions are appreciated. Thanks.
