On Friday night my puppy (10 month old beagle) was suddenly really lathargic, wobbly, practically falling over. We took her to the vet and they admitted her for the night. Pumped her full of fluids and she was released the following day, back to her old self. The vet figured she ate something toxic and his was why she was like this. She has been fine since we got her back, running around playing like normal. We have not taken our eyes off her and suddenly she woke from a nap, threw up, and now has the same symptoms she did on Friday. Eyes are glazed over, wobbly, and lathargic. We are about to take her back to the vet. Any ideas what this is about??
