This might sound a bit harsh to some but I think it is typical human selfishness - putting our needs i.e. being bereaved of a loved pet before the problems that an animal might encounter through being a clone. One has to remember the feelings of getting to know your dog and how your relationship developed. This will happen again with another, different animal - it won't be quite the same but still as wonderful in its own way.
There are so many lovely animals that need loving homes, I wish more people would consider this option. My two rescues are delightful and I have met countless others. The other day, I met a brilliant dog (staffy/collie cross) with one eye who had been abused when young. He is now a fantastic young man who is brilliantly trained and a dog to be proud of. Maisie fell in love with him at first sight because (unlike quite a few pedigrees we have met) he was well behaved and didn't rush up to her trying to invade her space and pushing in between her and me. He just played nicely with her. Another lady I know has got two fantastic lurcher crosses and I know quite a few 'jack russells' who are like mine, of very dubious origin and they are all lovely.
Instead of cloning animals, contact your local dogs trust, RSPCA or Battersea - or any of the other myriad of charities out there!
