i usualy take my 3 dogs out seprately but today i was running late so i decided to take my 2 bitches together(big mistake) i was walking down the street when we passed a woman they both started to bark it took all my strenth to hold them back and when we got into the park we met another dog one they had both met lots of times they chased the poor dog darking at him and i could not get them to come back( when i walk them seperatly the are both very good and are fine with other dogs) Does any one have any ideas

Pack order maybe ? 

I have read this sort of thing before, I think it is down to them being a bit too confident when they are together. Some one else will be able to tell you more....

Good luck :D

When you have more than one dog they have to be trained to walk separately and together ;)  this is why most owners recommend having at least a year between dogs ;)  it does take far longer to train the dogs and walking in tandem or in threes takes as much time and effort to teach (if not more!! ) as teaching one to walk nicely.  Perhaps you need to go back to basics one single walks and tandem walks ;)  And make sure they all recognise you as boss ;)

i will start doing that thankyou( this does not happen when i take out the male out with one of the bitches) there ages are 5 3 and 1 so i have left over a year gap
