My Jack Russell is 5 years old and we have had him since a pup. He was perfectly house trained at just a few months old. About 3 months ago he started weeing everywhere in the house - he will wee against the beds, against clothes hanging in the wardrobe, he will just about pee against anything. He started taking seizure medication about 3 months ago and this is about when this problem started. He has always been an inside dog but we are at a loss with this problem. When we are home we leave the doors open all the time - he will come inside - look at us and lift his leg to wee - knowing full well that he will be put outside and growled at. Can you please help? We are desperate!
