We had a singleton and she started to become food aggressive and pushy by 6 weeks old. My vet advised that we take her to be socialised as soon as possible as risk of infection was far out weighed by risk of being destroyed should the behaviour ever get out of hand when she reached her full 45+ kilos. I spoke to the dog club and as long as we were happy to sign the waiver that we wanted to join the class early - she could go.
By the time she was 13 weeks old, she was fully house trained, had passed the kennel club puppy foundation course and had learnt manners. We did indulge her at bedtime as mum wasn't happy to sleep in with her at night from 3 weeks on wards and we knew she'd get cold if she wandered off the heat mat so she slept in a bed next to us and we made sure we got up to make mum feed her until she was ready to be weaned. She came everywhere we went as there weren't any siblings to keep her entertained or to snuggle up to but that's as far as the indulgence went. The new handler was very impressed with her and amazed at how much she had learned. We just did as our vet advised and kept her busy with proactive teaching and tiring her out enough to keep her happy and quiet.
It's all down to what you do with them and as I was home alone with her and the other dogs, I could take sole responsibility for her daily routine and when to pander to her diva moments and when to ignore them. Had roles been reversed, my husband would have created the pup from hell!
