Poor Shelby - we were on vacation with her last week, and Friday morning she started with diarrhea. We immediately stopped all treats and only allowed her to eat her food. She wasn’t going to the bathroom any more often than usual, just when she went it was very loose. Called the vet on our way home Saturday, put her on a bland diet of hamburger and rice and made an appointment for last evening. Vet says she has colitis - will probably never figure out what caused it. Put her on antibiotics and continue the bland diet. Other than these loose stools you would never know anything was wrong. But when they weighed her she lost 2lbs in 4 months. Vet wants to monitor her weight. I am not concerned because I try to keep her at 25lbs so I do adjust her food based on her weight. And all her vet visits she varies between 24-27lbs. She was 24.6 yesterday. We recently changed her food about a month or so ago and I was feeding her the same amount as her previous food, not realizing we should be feeding her almost double. I feel absolutely horrible about that. I know that when I would have weighed her I would have increased her food but with her being sick I can’t do that and she was at 25lbs a few weeks ago. But so far no bowel movements since yesterday afternoon. Stool sample was negative. Vet says that is good and it is ok if she doesn’t go for a few days. So we are hoping the antibiotics are working and she can soon get back on her food. If not then we will need to do further testing. But vet doesn’t feel there is anything really wrong with her other than a GI bug. She did get a complimentary butt trim by the vet. It just breaks my heart, she doesn’t understand why she can’t have her treats.
