We have 2 border collies that are advancing in age. The male is 14 and and is still very active, but beginning to slow some. The female is 12. She's slowed down and mellowed out considerably, and physically is having trouble with stairs. She gained alot of weight and we switched to the senior food with the condrichton about 3 years ago. They both still have hearty appetites which is encouraging.
They have been such a huge part of the family for so many years it's hard to see them get old. What a joy they are. Unconditional love. They know your moods, and your schedule. They know the sounds of the home like the garage door, front door opening, your footsteps, the fridge, MICROWAVE!, power tools, you name it, they have a routine based on yours.
Best of luck with your pooch and we'll be thinking about you guys today.
Good dog.....
