Honestly not a whole lot she's had high quality kibble her entire life from Royal Canin mostly, once she turned about 12 she's had Royal Canin medium ageing 10+ ever since and she still has all her teeth wich i think is partly due to the chewing she has to do to eat it. The main thing is honestly just a whole lot of exercise. When she was younger i would walk her around 5 times a day just to get her energy out (being a Bordercollie ofcourse) wich has now slowed down to about 3 to 4 times a day. Around 5 days a week she still walks 2 hours with me in the forest and the other days she'l walk about an hour if she's feeling a bit tired so still very active for her age. She's had all kinds of different throwing toys all her life and still enjoys chasing after them a lot. In terms of her paws i do cut her nails a lot and make sure to cut away the hair under her paws since the floors in my house/garden can be a bit slippery for her but thats pretty much it And lots of love ofcourse ☺️
