Locke the whippet is 2.5 years and still squats. Not sure if he'll ever lift? Abby lifts - she doesn't aim to pee on anything, but there is definitely a lift going on there. I can't quite remember when she started. I do remember when I went to the behaviourist when she was about 15 months old, she did ask me if she lifted her leg. I answered yes and was really perplexed with the meaning behind the question but I didn't ask why it was of interest. I should've - I would love to know what/if it means anything.
