Hi again Shannon,
Thanks for your quick reply. There are a few things that could be going on here, and while it is most likely that your girl just has a bad gastroenteritis, however there are a range of other possibilities ranging from a toxicity (eg rat bait) to a intestinal foreign body or even just a diet intolerance if she has been changed on to a new diet without a transition period. Hopefully the vomiting has settled now - and if it hasn't, I would encourage you to get your girl checked over first thing tomorrow morning if possible. I would also recommend checking your yard for anything she may have gotten into. As above, rat bait can cause blood clotting issue and hence blood in the poo like you are seeing. If you, or your neighbours, have any rat bait laid down then this is a definite possibility and reason to visit your Vet first thing tomorrow morning.
Whatever the case, you will need to start your girl on a bland food for the next few days. For this, cooked boneless, skinless chicken breast is ideal along with boiled rice. I would also like you to keep a close eye on her mucus membranes, capillary refill time and respiratory rate for the next few days as follows:
Mucus membranes - flip her lip and look at the color of her gums. They should maintain a nice salmon pink color. Get her to the emergency Vet if they appeal white or very pale pink, or if they are a dark deep red color.
Capillary Refill time - this measures blood perfusion and test this by putting your thumb on her gum to apply pressure. After you release your thumb you will see the gum blanch. Capillary refill time is the amount of time it takes (in seconds) for the gum to return to a healthy pink color from the blanced white color. If 2 seconds or less don't worry - if it is taking significantly more time, again - off to the emergency Vet.
Respiratory Rate - if she is continuously panting throughout the night this is a sign of shock and or pain and a signal for a trip to the emergency Vet.
You will also need to keep a close eye on your other 2 dogs, and if you notice any symptoms from them, then take them and a fresh fecal sample from each dog to your local Vet if you can. For now, continue to try and coax Bailey to keep drinking. If she isn't so keen, you can try her with a fresh chicken broth. Just boil up some chicken, scoop off the solids and feed her the luke warm broth. Finally - make sure all dogs are up to date with their deworming treatments and use a reliable allwormer for this such as Drontal or Milbemax.
I hope all of the above makes sense? Please let me know if you have any other questions. My goal is to provide you with excellent service – if you feel you have gotten anything less, please reply back. I am happy to address follow-up questions. Thank you for your business and I hope to work with you again soon!
