Is your harness a perfect fit?
Yes
How does the PerfectFit Harness benefit your dog?
My 4-year-old samoyed has some reactivity issues around certain dogs (specifically the psychotic border collie cross down the road) so having the front-clip allows me to correct her without risking putting pressure on her throat. My puppy hasn't yet learned to walk well on a lead, so while the harness gives her a bit more power than a collar would (she is already 19kg and very unaware of this) she has been walking better on-lead since we got her one.
