I canix my 40kg doober in a snuggle pets harness and they are awesome we got our waist belt and bungee lines from snowpawstore

we used the first one for 3 years and only got a new one as it started to look a bit lived in but it is still going strong and we've just lent it and the rest of the kit to another doober and mum who are just getting started as we are off games for a while.

I use the Manmat Delux shoulder harness for our dogs when canicrossing. Nice and comfortable padding and quick drying if they get wet.

I also use the manmatt bungee lines and a Kisi walking/canicross belt round my waist.
