no,lol...you can't squirt them...and actually...after you come back from your walk is the PERFECT time to start the training.....when I have people's dogs that I train...we go for a 10 minute walk FIRST...then train for about 20...walk again for 10,a bit more training and then a short relax,play time before leaving each other!! good luck!! and remember...this is a full time commitment you need to make to them and yourself!! :)
