We've used these for the last three years, all that goes in them is food in Ziplocs, water in 500ml bottles and a rain jacket - Ruby the GSD decided to go swimming last year, in a big stream / small river, the backpack initially became a buoyancy aid, carrying her downstream, it then became waterlogged and stopped her climbing out.... Thankfully I had her on a search lead so I could retrieve her before things got too serious. The Ridgeback is in no danger of doing anything similar, she'll reluctantly go ankle-deep and no further!On longer walks keep an eye out for chaffing Under the armpits*** we had to fit some addittional padding in 1 or 2 places
Oh and if they swim it wont stop them, so if on a overnighter - when applying Dog can carry its own kit you may want to reconsider the towel
***yes I know but - its a good descriptor - you know wher i mean
The Hurtta harnesses don't seem to cause any chafing but are a bugger to get adjusted - and readjusted for seasonal weight loss / gain. Good kit if a little expensive.
