I used to babysit Otis's little brother all the time, and I understand your frustration that Mylos' parents don't handle their dog in the same manner you would. (BTW, I hope Mylos' parents don't log on to YorkieTalkand read this!)
One thing you might want to invest in is a "coupler." You can find one at the pet store. It makes walking two dogs sooo much easier, and it's not expensive.
Here's a pix of the coupler. |
