Hi, my beautiful 7 month old lab came into season yesterday. She's a bit stressed and restless and gets very upset when I've tried to introduce puppy pants. The problem is she is completely in love with and quite reliant on her 10 year old neutered (non related) lab brother and only started sleeping through the night four weeks ago when she moved from her crate to his bedroom (utility room). He has had a bit of a sniff of her and he's smelling the blankets that she's using but I don't know if I should separate them again overnight? I don't want to increase her stress but equally I dont want him bothering her? Or should I try again with the pants? Or does anyone have any other suggestions ? Any advice would be welcome. I've only ever had dogs before, she is my first bitch.
