We adore our 9 month lab Lola but i am begining to wonder if it has all been a huge mistake ! She is great with our children and we wouldn't be without her now we have her but her behaviour seems to go one step forward and two back ! She has been to classes and is very clever and would do anything for food but she has all the lab traits in excess.She is very destructive and has caused hundreds of pounds worth of damage in the house , clothing and garden. She is a very big girl and jumps up alot which is quite frightening for strangers and especially children who visit, she is not aggressive but people do not realise this. She pulls badly on the lead despite one on one training with a trainer. Our visitor numbers have reduced considerably.We are very firm with her but she just can't seem to help herself.Is this just puppy behaviour and will she grow out of it ? I am reaching my wits end and feel i have tried everything and this is just going to be the way it is. Am i the only one ?
