Up to now, nothing got rid of her diarrhea except hydrolyzed protein kibble, which is expensive!! I tried another brand of grub food, didn't help. I have tried all the various "novel proteins", nothing helped. I always ended up putting her back on $HP. Until Jiminys Cricket food!! I thought -- this is the last thing I will try, then it's $HP for life. Well, it is working!!! I was making the switch verrrrry gradual to not upset her tummy, and got to 2/3 Cricket, 1/3 HP. She started having occasional diarrhea, usually when stressed over a new situation or getting hold of something she should not eat (hair ties, string from rope toy, etc) ... she is very sensitive, physically and emotionally (rescue dog). Anyway ... I backed off to 50/50 Cricket/HP, and we are holding steady with no diarrhea. I may just stick with 50/50 and be thankful, at least I can cut the $HP in half, and that's a savings. She is only 1 .5 yrs, maybe as she matures and settles down we can inch our way up again on the Cricket food. For now, I'm happy and love Jiminy's!! Side note -- my cats love the Jiminys too, and keep clawing holes in the bag to get a piece!! I keep taping it up and reminding the household to close the pantry door so they can't get at it!! :-)
