How to stop my dog's mouth bleeding with slow blood clotting?

Updated on September 23rd, 2025

Pet's info: Dog | Mixed Breed | Male | 11 years and 3 months old

My dog has been bleeding from his mouth and has a bad odor on his breath. Took him to a vet yesterday and they didn't find anything except did blood clot test and said his blood isn't clotting as fast as it should. She put him on vitamin K and said come back in a week for test and see if it is working. Meanwhile his mouth continues to bleed occasionally. Not as bad but still enough. Is there anything I can do to stop the bleeding once it starts. Sometimes takes about 30 minutes to stop.

Hello and thank you for contacting Petco Pet Education Center, formerly Petcoach. There is nothing that you can do once the bleeding has started but there must be an underlying reason for the blood clotting disorder and mouth bleed. Excessive bleeding from the mouth is usually a result of gums inflammation or bath teeth. If you feed your dog only soft, wet food, hopefully there will be less episodes of the bleed. Blood clotting disorder could be a result of low platelet count or clotting factors deficiency. All of these problems have their underlying causes which should be investigated. Please, talk to your vet about running more tests to find out why Duke's clotting time is delayed and why he keeps bleeding from the mouth. Mouth bleed can become an emergency, if it is profound or prolonged.
