So this is frustrating to say. But I have a 12 week old BLF haven't done much but socialize introduced to water and about 5 those in a hallway a day up till 10 weeks!! Last week moved her outside on her marks and she was doing good, a couple times my wife would throw them fro about 15 feet in front of us and Tess would go get them good and bring em back to me. The past few days she will go out there and just lay next to bumper. I put a long line on her and when she gets to it and puts her mouth on it I blow whistle and tug a little to bring her in and she just bites the rope and runs in! I don't get mad I simply just go get bumper try it again and it doesn't work so I just stop for the day. Now my question is, is there something I should be doing? Is this normal at this age? What should I do?
