To think a pet dog should not be buried in mutual gardens?

I just looked at this. Sleepy Meadow Pet Cemetery and Crematorium, Mill Lane, Moston, Sandbach,Cheshire
These are the costs. (I don't know how up to date it is.)

Pets are cremated individually and are returned in a disposable container
Small Pet£34
Cat/Rabbit£76
Dog £91

My back garden has anumber of deceased budgies but dogs are a very different matter.

I think burying anthing bigger than a small pet dog in any urban garden is not really appropriate.

I think the other owners should be consulted, perhaps if she had the animal cremated and buried the ashes, perhaps planting a tree or bush over the spot.

I know someone who had a call from the previous owners of their house. The request was could they come back and dig up the dog they'd buried over 10 years earlier, at the bottom of the garden. Yes they could and they did. Imagine!

Good job we're not in a shared garden. We have three Jack Russells and a Chihuahua buried at the end of the orchard. The ashes of a German Shepherd and Rhodesian Ridgeback under the trees at the back and DH's beloved golden retriever is buried in a copse just a couple of hundred yards away on the farm he used to manage.

We'd better keep quiet if we ever put the place on the market

I would take a dim view of dogs buried in shared gardens, need to check deeds and leases for shared premises. We have a flat that states clearly in the deeds that no pets are allowed under any circumstances. No matter how well loved your pet is the next owner may not be keen to find it when creating his garden.

Seems a very odd thing to do in a shared garden. Think a pet cemetery would have been more appropriate.

Do you have a management committee or owners committee for your flats mcem? Who it responsible for maintaining the gardens?
There will probably be covenants or rules about what is allowed in common areas. Any committee should at least be consulted.
We visited Tangier Island in Chesapeake Bay a couple of years again and many of the houses had family graves in the front gardens.
I have to say I wouldn't be keen on any remains, human or otherwise, in my garden.

I don't know about shared gardens but one of our neighbours buried his very large dog in the garden in a coffin. We wondered if he took it with him when he moved but have never dared ask the new people. When I say new, they have been there for over 15 years so if the dog was still there they must have found it.

If everyone has pets mcem you could end up with a graveyard. You could suggest to her that there are such things as pet cemeteries.

What an interesting question. I helped dig the hole in my parents garden after their old dog died. We dug very deep, not least because their house backed onto fields and foxes were regular visitors. We buried the old boy in a sheet, covered him with soil and put stones on top until mum planted an apple tree on the spot.
I don't know if what we did was illegal but it was their own house, rather than a communal area.
Do you think your neighbour would be amenable to paying for a cremation. She could then bury the ashes, or scatter them in one of the dog's favourite spots. If the burial does go ahead, it's important to dig very deep to avoid some other creature digging the body up.
