So sorry Jon, only just seen this as we have been away for the weekend
He was a lovely boy, and it's so sad when they have to go. I am glad you are considering another dog, he/she will never replace Jasper, but you love your doggies so much and will give a fab home to another woofy friend when you are ready.
Quite a few years ago when my chum Zeb died we decided not to get another dog, too tying etc.. lasted 2 weeks

Its pushing 20 years since Zeb died, we still talk about him regularly and his little habits that made us laugh ( he was a border collie cross, and a right little b !). We lost Rufus nearly 5 years ago at 15 yrs, he left such a massive void but getting Ella helped so much - she is so different to him. They all have their own personalities and are so different, but one things for sure they never leave you.
Jasper had a wonderful life - you both did him proud.
Thinking of you.
