Query: Had problems with larger strong dogs

I used the sporn for 2 large huskies; I found that when one dog pulled, the other suddenly had a much shorter lead. In other words, the locking mechanism to keep the lengths of each lead as I set it didn't lock well enough to keep the leads from changing lengths when one dog pulled and the other didn't. Possibly it was defective but I came up with a new solution so just returned the sporn rather than exchange it to try again.
