First male adult is 7 yrs and not the friendliest the other is 5 yr female total mush - rescued 8 mo pup who wants to play play and play adults growl and show teeth and snap - I'm scared - we admit the introduction was wrong - we give more attention to the adults with petting - play and treats - as soon as puppy comes around all hell brakes loose - is there any way we can fix this - thought of getting muzzles for all 3 - it's when they are in the backyard they are at their worse - the pups still thinks its play - I use a cane to get around and have use it to push them away -- bring toys to distract - would appreciate any advice or tips thank you - my heart is pounding so fast from seeing them like this
