Best harness for dogs active dogs

Hi All! My two KC Cavalier Spaniels have the run of my fenced property. They dig, they forage…I like to have a something on them that I can put a bell on, especially the older, as she’s deaf. Nice to know where they are. I have 3 kinds, and none of them stay on despite my adjustments. Curious if anyone has a fave. I did search the archives by the way!

I have the Balance harness from Cleanrun.org, who has the best customer service. They are super helpful and respond to emails very quickly.

I also have the Front Range and the Hi & Light harness from Ruffwear. The Front Range is a little heavy for our OK summers so I tend to use the Balance Harness more often.

My dogs are Miniature Schnauzers if that helps and are roughly 12 pounds. One of my girls gets out of harnesses very easily but has not escaped from the Balance Harness or the Front Range.
