Dog ate weeds, now has diarrhea & vomiting. What should I do?

Updated On September 23rd, 2025

Pet's info: Dog | Australian Shepherd | Female | spayed | 8 years and 8 months old | 44 lbs

Dog had diarrhea and vomited in crate today while I ran a morning errand. She has had more diarrhea when taken out throughout the day. When husband got home I asked if she had normal bowel movement on her morning walk and she did. Then he said she ate some weeds (she likes young dandelion leaves etc) but he didn't know the neighborhood sprayed earlier this week. Assuming this is what caused the GI issues, Still eating and no other sx. Other than hydration do I need to do anything for her?

You can try a home remedy on Belle to see if that helps before having to take her into the vet. Withhold food for 12-24 hours, then feed a bland diet of boiled white meat chicken (no bones) and white rice in small amounts several times a day for a couple of days. Then slowly add back in her normal diet. If the vomiting continues in the absence of food, she vomits the bland diet, the diarrhea continues on the bland diet, stops drinking water, starts vomiting water, or becomes very lethargic, she will need to see a vet right away.
