my 18 month old lab ate his seresto flea and tick collar. He vomited up his breakfast and pieces of the collar. Will he be ok, or should I have a vet see him?

I am sorry to hear that Max is going through this. I don’t know how long ago he ingested the collar but I am concerned. I would highly encourage you to have him evaluated by a veterinarian as soon as possible. X-rays may be recommended to look for an obstruction as well as blood work to evaluate For possible toxicity . Depending on how sick he is they may recommend keeping him on IV fluid therapy for a while. Best of luck and I hope he improves soon. Thank you for using Pet Coach.
