Pet's info: Dog | Mixed Breed Small (up to 22lb) | Female | unspayed | 1 year and 1 month old | 4 lbs

Is my dog poisoned? This morning I woke up to my dog throwing up foam. She is epileptic, but I've never seen her have a siezure like this. She takes phenobarbital and im starting to wonder if I maybe gave her too much. I have to cut the pills into fourths and my cutting wasn't very presise. I also found some lint torn up in my dryer room. She is a 4 pound chihuahua pomeranian mix. My vet dosen't open until later in the day. Should I take her?

While toxins could cause vomiting there are many more common causes ranging from a bowel obstruction to intestinal parasites. An overdose of phenobarbital would not cause vomiting: I would expect to see sedation or difficulty vomiting. If she had a seizure that is atypical for her, or if her vomiting continues I would recommend taking her to the veterinarian later today. I would recommend withholding food until you can see the vet. A little water should be okay but don't let her gulp an entire bowl.
