I'm no help. We had to move to the country when we hit 5 dogs 35 years ago. Bad idea, they just kept expanding. People dropped them off, we found them abandoned, they found us- my husband says there's a sign in the sky that only dogs can see, points down and says "Sucker Tucker". When we hit 21 we knew we had to stop, we couldn't look after any more. As we get older that gets harder so we are TRYING not to add when we lose one- except for Kody, then I had to get Thunder. Now we are at 12. So as far as I can tell the only cure is age. It took us 35 years so just have patience.
