Oh my heart does go out to you.
It is such hard time when we start to have the thoughts you are going through.
I always say when a dogs dignity goes then it is time. So long as she is still enjoying life, eating and is able to wee and poo then there is no reason why she should not continue.
I would be dictated though on the walking and let her walk you rather than you take her for a walk as she may be pushing her self a bit too much as she wants to please her mum !
I think you will know when the time has come and be brave when you make the descision as it will be very hard but something that will be the best for your little girl.
Take Care and enjoy each day with her.
Lucy
