Two Dogs - trying to leash train
We have two four and a half month old puppies - brother and sister, Max & Molly. We are having problems getting them to walk on the leash without pulling. They are always together so we try to take them out together but we are now wondering should we take them out individually even though the other puppy will howl and cry when left on their own without their sibling? In general they are pretty well behaved - Molly is a lot more assertive than Max and although not always 100% obedient, they are getting more consistent. We also notice that when we try to get them to sit when they are out walking, they take a longer to respond than when doing focused training with them in the back yard - is that typical?
So - do we walk them individually or teach them to walk together without pulling on the leash? Any suggestions would be really appreciated.
