My 8, nealry 9 month old Cockapoo is barking at me and my partner when we walk through the door. She knows it us but carrys on and when we tell her no she growls at us.
Its been happening alot recently and now it can just be us walking down the stairs and she will growl or bark at us.
Hi it sounds to me that your very intelligent CP is trying to tell you something. Telling her 'no' and your voice tone may make her growl. Never tell a dog off for growling, it may be a warning, if you stop the warning a dog may be prevented from giving one and snap instead.
My puppy is a barker and a growler, I am learning to 'read' them . She often barks 'insistently' when she she wants something from me like to go out and I have not noticed her by the door. She barks to go for a walk , when I am on the phone ( I am speaking to someone she can't see which is confusing) , when I come downstairs and she has been unable to follow ans she has been waiting for something . Growls have different tones for different situations too .
When you come downstairs and she barks /bend down/call her to you reassure her 'its ok' in a calm tone and praise when the barking stops.
On walks take treats with you , when she barks turn and walk the other way saying 'quiet' in a calm tone /treat and praise when quiet . Repeat many times.
My 6 month old puppy barks at the slightest shadow on my front door. When she does I call her to me in a calm voice no anger / she stops barking / I say sit 'good girl' . She is only doing her job of protecting her space and I am saying job done you can stop now i have got the situation under control.
