My dog is gagging and threw up grass. Why is he still gagging?
Thanks for using Petco Pet Education Center, formerly Petcoach. It sounds like Auggie could have either some nausea or had something caught in his throat.
Reasons a dog might vomit or retch (the gagging without producing anything) include eating something new/different, toxin, infection, organ disease, cancer, or other. If he’s just vomited once, pick up the food and water and monitor. Reintroduce water 4 hours after the vomiting episode and a small meal 12 hours after vomiting episode.
If Auggie has vomited several times, it’s time to head to the ER clinic. The veterinarian will do a good physical exam and may recommend x-rays and/or bloodwork to help narrow down the cause of the vomiting. They can also treat the nausea and administer fluids for any dehydration that has occurred.
Best wishes to you and Auggie!
