We have an 18mth old female who was fairly well trained. She was partial to trying to chew my pants and socks, turn the bin over, jumping up and digging but there was much improvement ...ALMOST sorted. She had menstruated twice on the advice of the breeder and then we had her ‘done’. She seemed fine for about a fortnight afterwards but now she has reverted back to her old behaviour - trying to chew my pants and socks and all the other non desirable acts as well. Is this normal? Do we have to go back to puppy training again or will she calm down ? Any advice or experiences appreciated.
