Try K9active in Rosyth, its in the old fire station building on castle road
https://www.k9active.co.uk/dog-harnesses/just been in to their well stocked shop yesterday and my Westie tried on Hurtta, ruffwear and rukka harnesses
(Hurtta and Rukka both finnish companies)
I never realised there was a shop there and I live in dunfermline, until doing similar research this week and checked out stockists as wanted to try them on and feel/see what looked like before shelling out
excellent knowledgeable service and selection of harnesses, had all sizes and colours and also a brilliant selection of quality natural dog treats, Cody particularly liked this bit of the shop and resulted in few treats coming home...
A family run business that i will now be supporting rather than local pets at home,
reading their website blogs I really like their business ethos.
Ps
i bought the ruffwear front range harness and matching collar for everyday use, but will probably go back for the more substantial flagline for next years hillwalking outings as like having a handle for lifting over more common fences find on Corbetts and Grahams
