Confused by different things I've read and also from our dog-trainer - about whether or not we should ignore our pup when he bites - us or our clothes - or yelp (high pitched or low pitched? which one???).
Rollo (9 weeks and 2 days) now constantly nips our clothes and hands - not too hard but enough to put off the DCs. At first, I told DCs to stand still, tunr their backs, ignore, walk away. This had no effect on pup - who then would either keep holding on to clothing item or - especially - follow the person walking away and jump up and bite/hold trousers.
We were also constantly substituting the clothing/ hand with a soft toy for Rollo to chew instead.
Trainer told us to yelp, say "Drop" (a command he's just started to learn but doesn't much comply with) or "Sit" - an alternative behavviour to biting /jumping up. She's also told us NOT to substitute with a toy as this is just encouraging further chewing/biting behaviour.
Several 'play' sessions with DCs have disintegrated within minutes with DCs both yelling "Drop!"/"Sit!" again and again and again. I'm sure pup thinks this is part of a game. He certainly doesn't stop nipping/ jumping up.
My instinct is still to substitute with a toy, as withint the split seconds of this all happening, I want to avoid the DCs being bitten and by shoving a soft toy into Rollo's mouth, that immediately prevents him biting the DCs. But am I doing the wrong thing?
Can someone very experienced with training out this behaviour please give me a step-by-step account of exactly what to do when pup nips/ jumps up/bites clothing, please?
