The prevalence of various clinical signs was evaluated in 97 dogs with brain tumours. 33 breeds were represented; Golden Retrievers were most commonly affected. Most dogs were older (median age, 9 years); 95% of dogs were >=5 years old. 76% of dogs had tumours in the supra-tentorial region. Seizures were the most common clinical sign at initial examination, with lower prevalence for circling, ataxia and head tilt. Meningioma was the most common tumour. It is concluded that brain tumours develop most often in dogs >=5 years old and are uncommon in dogs <5 years old. Seizures are a common clinical sign, and a brain tumour should be considered in dogs that have their first seizure after they are 4 years old.
