I have a brand new/tags still on blue K9 sport sack rucksack carrier just like this:
k9 Sport Sack
They're very highly recommended and I brought back from the US as my dog is getting older and thought he might like it but he's not too keen... Maybe it's an old dog/new tricks kind of thing. It's a size M / Cobalt Blue. To ship one here is estimated at £59 + £21.
Asking £50 - located in SW4 if you want to come test out size or anything before deciding
Pls ring 07709 55 66 91 if interested.
