I use the Clinistix because to me there was a more drastic change in the colors. There's only 3 color variations and it goes from pink to purple..not green to a little darker green in the first color change.
Hey about the feces. My princess, Chiomba Dayo, had dark feces as well. Brought her to the vet and they said it may of been blood. Some tests were done and $ was spent to find it wasn't blood but bilirubin. apparently its caused from to much stomach acid and or the liver not being able to break up fats… We were told to try a low does antacid, over the counter no name brand. This improved her feces color and her appetite! But its just one more thing to do every morning. I feel like she owns me, not the other way around.
No offense intended, but the Beloved Bulldogs site was not written by a vet and seems a bit dated to me. Having had a dog treated for heartworm years ago, believe me the arsenic treatments can be dangerous and painful. (See above link)
Sometimes Gypsy seems to have seizures in her sleep. Not the kind of movement wherein you guess she's chasing rabbits in her dreams or something. She does that also, but sometimes it looks very much like a seizure.
