Too much exercise!

Here I am with my new friend Charlie, the border collie.

His Mum called my Mum because Charlie had been aggressive towards other dogs, particularly small dogs (that was a worry!) It turned out that when Charlie went out his Dad liked to play ball with him ALL the time. Charlie was fixated on the ball so when another dog came close, he would try to 'see it off'. Mum said to try cutting out the ball play and see how thing went. Charlie's Mum said he became so much calmer, really quickly.

If dogs get too much exercise or stimulation they can find it really hard to calm down and relax. Mum says if, after a nice walk/run, a dog doesn't go home and have a good sleep, if the dog isn't relax and chilled, then the exercise has been too much.
