My Mum has a 15-year old dog (poodle and bichon frise mix). He has slowed down recently but he is in fairly good condition. He is deaf though and suffering from cataract.
Last week, he screamed randomly, as if he was in pain, a few times. Initially, it happened when he was on a walk and we thought he had hurt his legs but we checked and there was nothing and he was not limping.
Nothing has happened for the past few days but he screamed again twice today.
Has anybody got any experience of this and what the cause might be? Could some internal issue (tumour?) cause him sudden and occasional pain?
Thanks for any advice.
