Our lab seems is showing some major behavioural red flags when we welcome strangers into the house.. I wonder if anyone has gone through this and come out the other side with a calm, happy dog? It is with strangers only and he used to bark then calm down when they came into the house, but recently we have had more people pass through than usual (still not loads!) and noticed he is much more stressed.. hairs go up, he growls and lunges at times also. We really have so few strangers come into the house, I guess he hasn't had much practice with this particular situation. Outdoors he isn't bothered, he is interacts with other dogs and people without any fuss and those he knows, he Loves! He is 18 month, in good health, well exercised but does have a slightly shy nature which we have been mindful of. With friends we have managed it by asking them to interact a little with his ball and treats ... making things as positive as possible.. without being in his face.. which seems to work, but it's not suitable for all environments and people.. and I can see the slippery slope we are on! We are also trying to desensitise him to the door bell so it doesn't trigger the crazy in him as thought it'd help him be calmer when people come through.. he is very clever and good at picking up commands Any wise words would be very welcomed! Thank you!!
