sisco , i only use the chain for show practicing as i will be using one in the ring with him , not sure about the other harness as i have never used one , but i walk all mine on a collar & lead .
i have 4 dogs at present, 2 are oldies & 2 youngsters, i don't find them too much work to look after. I walk them together most days. mishka gets a run in harness & the pup will be starting to run in harness too once a year old . 1 border collie & 3 siberian huskies. They are quite well behaved...
