4 lbs? WOW!! The pictures I saw, he LOOKED like a Tank

I'll have to go back and look at them.
I used to have a yellow lab (that ran away

) and he was VERY careful around Tucket, who is only 4 1/2 lbs now, and he still accidentally stepped on him on more than one occasion. He would try SO hard not to but Tucket gets underfoot when he is playing. Definitely keep an eye on them when they are together. Someone mentioned an x-pen? That will save you a lot of stress

I wish we had one when we got Tucket. Now we don't need one but I stressed all the time when we first brought him home because dh had just laid laminate floors and I was always chasing him around not getting anything done unless he was in his crate and I didn't want him in his crate all day. Anyway, that's old news...he's doing great!!
