Hi everyone, thanks so much for taking time to read and help.
Firstly I spoke to my very dog experienced colleague. She said that she completely understands the plight of the dog but to go in guns blazing and do what I had planned is not going to get success. I wanted to knock on the door and talk to the lady and express my concerns gently and suggest rehoming.
She said the dog needs to be given up for rehoming but the trick is convincing the owners of this. Currently the weather is good (apart from a turn today to autumn!) and so they will not be feeling uncomfortable at all. At the weather gets cold and nasty there will be more clout behind the sentiment, 'I think he is not doing well in this situation'. She said I need to observe and be friendly and interested in the owners and not make any comments yet. I need to drip to them basically. In time it may start to dawn on them that the dog issue is a PITA and they hopefully will become ripe for the asking. Even though I can't bear to leave him like this each day I think she is talking sense. Offering to walk the dog is not the answer she said, it suggests criticism of them and also they will just drop their evening time thirty minutes to the shop and back (most days they do this, at around 8pm) if I walk him. Its the other 22 hours that he spends completely alone that is worrying.
He is such a good dog with good behaviour, whimpers quietly and does not go overboard when they do take him out! He emerges from the yard sort of blinking at the road at the world outside. But I am scared that over time if he is kept like this he is sure to develop behaviour disturbance.
The next thing I did was get in touch with the labrador rescue charity in my city. They have some members near me and I asked if they would observe/ educate when the winter comes on a bit. They said they might do, but seemed reluctant, I know its a big ask. They sympathised but like a lot of poeple are saying it is not actually an illegal situation. They said they would be able to home him swiftly if the owners gave him up.
My next door neighbours and I are both grappling with the wish to home him ourselves, my husband is softening and can see how much it is affecting me and he has been here several times before! It is a massive undertaking but if I 'rescued' him it would be quite hard to let someone else have him! This would take great thought and consideration though, I know.
So my plan is to wait, observe, approach her on one of her walks in the winter, just be upfront and say that I think he is isoalted,etc, have they thought recemntly about homing, can't the dog come inside at times, what about some antihistamines etc. Just be friendly. If there is no no no to all of that through the winter I am going to come on stronger, eg, say that I feel it is a bad situation for him, ring dog warden, RSPCA to go out and do education.
What do people think?
