I have a 2 and a half year old lab bitch she seems to have been in season for ages. I have decided to put her in pup. We have been and visited a dog (first time for him) and they had a great time, played for about 45 mins then she started standing for the dog, but his aim was wrong! Day 2 arrived and was more productive, my dog stood but yelped as the other tried to do his job now she sits when he jumps her. is this nomal?
