My dog licks floor and vomits. Is it allergies or stomach issues?

Updated on September 23rd, 2025

Pet's info: Dog | Keeshond | Male | neutered | 3 years and 1 month old | 35 lbs

From time to time he will get in what I can only describe as an obsessive compulsive state of licking the floor - mostly it seems trying to eat hair and dust on the ground in an effort to make himself throw up. This can last anywhere from twenty minutes to a few hours and usually he feels better/returns to normal after he vomits. It reminds me of when dogs eat grass when their stomach is upset. Any ideas what might be the issue? Behavioural, allergies, digestion problems?

Hello, & thank you for using Petco Pet Education Center, formerly Petcoach. You have a good list of differentials, & all are plausible explanations for Oscar's behavior & symptoms. If this is a relatively new situation, then my first thought might be a food allergy has developed. It is not wise just to go out & purchase different foods. To do a food allergy trial you need a targeted food that requires a prescription from your veterinarian. He might want to try a round of antibiotics & stomach protectants first ( dogs can develop ulcers or bacterial overgrowths ). If you do want to try something at home first, you can purchase a probiotic called FortiFlora at most pet stores or on line. Feed 1 packet a day for 30 days & see if this helps. If no response in a couple of weeks, please consult your veterinarian. Hope Oscar is feeling better soon. Take care.

    Hello, & thanks for contacting Petco Pet Education Center, formerly Petcoach. I am so sorry for your worries with Oscar. The combination of a lack of appetite & a change in behavior makes me wonder if Oscar is some pain. This can be due to an infection, a blockage from an ingested object, a twist in his gut, or any number of possible serious scenarios. You should try 7 get an appointment with your veterinarian as soon as possible. Other than offering Oscar a bland diet ( plain chicken, white rice, low fat cottage cheese ), there is really no at home remedies I can safely recommend at this time without being able to examine Oscar. I hope he is feeling better soon. Take care.
