One of our wieners has the start of arthritis, the vet sold me Flex 2500 and told me it was good for all our pups. All the dogs are under 25 pounds and over 5 so they all got the required doze of 1/2 a chew. This was done last night at diner time.
This morning Thor my yorkie started throwing up and uncontrolled pooping

He got sick 12 times in 30 minutes and 2 more times on my lap on the way to the vets office. He was kept so they could put him on IV and gave him meds, lab work is being done also.
I have called and he is doing well but I need to know could the flex 2500 have done this?????? Has anyone had a similar experience????
