Welcome to Justanswer! I am Dr. Altman and happy to assist you both today!
First, congratulations on your new addition! With adoption it is very common for puppies to have gi upset and this can progress to the diarrhea, mucus and blood for what is called a stress enteritis.
I can give you some basic guidelines for today but if there is no improvement then please consider a veterinary er since these signs are signs of colitis (inflammation of the colon) and she is so tiny and can decline very rapidly. This can lead to more concerning illness and we definitely do not want this to progress. Below is more information on hemorrhagic gastroenteritis or HGE
- Begin Pepcid 0.25 mg/ pound (famotidine) every 12 hours for 3 days to help settle the stomach
- Wait 12 hours to feed to allow the gi contractions to subside that are causing the bloody stools
- Mix white rice with boiled lean meat such as chicken which is high in fiber but also bland to the intestinal tract and enticing to the appetite as well in small more frequent meals. No regular dog food please. You can add water to ensure that there is no dehydration but you also want to do water in moderation because large amounts of water will increase risk of vomiting
- If you are able, getting up and walk. Walks are great in reducing gi spasms, nausea, and entice the appetite even around the home or yard but if not up for it that is also alright
Indications of cause for concern:
- Gums are pale, yellow, brick red and sticky indicating dehydration
- Vomiting or diarrhea with blood in it that is progressing or not resolving in the next 2-4 hours
- Increased lethargy or difficulty getting comfortable
- Swollen abdomen
- Respiratory rate > 60 while at rest
- Temperature rectally <99 or >103.5
- No interest in food for 24+ hours
- No urination for 12+ hours
- Trembling without resolution for more than an hour
- Productive coughing
- Taking a "play bow" or what looks like a downward dog position which is abdominal distress
I hope this information is helpful. Please let me know how else I can assist you both today and I truly hope your dog is feeling better soon.
