Ok, so using regular leashes on walks has helped me tremendously!
Definitely not perfect- but much less barking and I am much more in control. Maybe we've run into less dogs lately, but the coins in the can are really helping, so I'm very optimistic things will continue to improve.
I'd definitely recommend trying the coins to anyone else having trouble with barking.
As far as the back yard- again the coins are helpful- but there's more of a challenge because there is so much more freedom for them. I haven't been able to experiment as much since we've been having a lot of rain.
MI Yorkielover - I'm so sorry- these little cuties really can make us feel like we are loosing our minds with the barking! And adding a second has been so much more to handle than I anticipated! Have you tried the coins yet? Or squirting with a water bottle? Do you have any way to confine your babies in a smaller area in the backyard? I sometimes babygate our deck to keep ours up there and the barking is much easier to address and manage. I must admit- I'm sad to hear that bushes don't help
