Hello and welcome. My name is ***** ***** I am an experienced small animal veterinary surgeon, I will be very pleased to work with you today and will try my best to answer your question to your satisfaction.
Glyphosate is a chemical commonly found in pesticides including Roundup. It is considered generally non toxic to dogs, however if enough has been ingested it can cause a gastro-enteritis, if this occurs it is usually transient and not too much to worry about
What about the raspberry coloured diarrhoea
There are some common sense things you can try but if symptoms persist you should have Abbie checked over by a vet, I will give you a few examples of common sense remedies
Hopefully the red diarrhoea is related to the Roundup and will quickly pass ...
You have told me nothing that I have not already found on the internet
Some owners try and control the situation with diet alone before they try anything else. This is logical and often works, the basis of this is to give the intestinal tract a complete rest and then bring it back slowly to function, resting the alimentary tract is the critical factor. It would go something like this ...A. Starve her for 24 hours but make sure she has access to water.B. The next day feed her four or five small light meals in the day. These meals should be the likes of chicken, fish, scrambled egg etc. with a little rice.C. If she picks up on this diet gradually reintroduce her normal diet over the next few days.3. Live yogurt added to the food can often help. Some gastro-enteritis situations are caused by an imbalance in the bacteria in your dog's gut. Live yogurt is full of " good " bacteria and will seed them into your dog's intestinal tract and restore the balance.
What about HGE
For a dog of your one's size a couple of tablespoons of yogurt twice a day would be enough
HGE is a possibility of course as would be other diagnosis, as I say if symptoms continue then have her checked over but if it is related to the glyphosate it could well pass 24 hours from now in my experience.
