We’ve been doing swimming this summer, but less so then last year. She needs help to keep swimming with her hind legs this summer. Underwater treadmill would probably be more helpful at this point as it would require more hind leg use. She seems to enjoy the swimming and seeing her doggie friend Milkway while she is there.
She has both good days and days that are more difficult. I judge many of her days by how well she is able to get up/down the steps, whether or not she plays in the yard and how much trouble she has getting up from laying down. The DM journey is full of ups and downs.
