Why does my dog vomit after drinking water and seem so thirsty?

Updated On September 23rd, 2025

Pet's info: Dog | Boxer | Female | spayed | 9 years and 4 months old | 60 lbs

My dog has had liver inflammation and is on medication. She is much brighter now, she also has a lot more energy and a greater appetite. However though, since she was diagnosed she has been vomiting only when drinking water. She can hold down food etc but she is always sick when she drinks more than 200ml at once yet she is also excessively thirsty all of the time. (the vet says she is hydrated still though) Is there any reason for this constant vomiting ? What could this be? Thanks Stefan

Thank you for submitting your question regarding Holl. She may be vomiting as a consequence of her liver disease (depending on the underlying cause of the inflammation) or she could have developed a separate problem. It is likely wise to have blood work and urine testing repeated. Be sure to have her checked for pancreatitis. She may even need an abdominal ultrasound by a board certified radiologist. In the meantime, you never want to limit water. However, you could offer her smaller amounts at one time to see if this helps. Be sure to continue offer it though so she can consume as much as she wants. I hope this information helps!
