To shut my dog in the garden for the day?

Ask your vet, the kennelling businesses, or local pet charities for suggestions?
Some towns have their own dog & cat groups on F’book, so no possibility of ’advertising’ your empty property, should you enquire there.

Imagine trying to shame people for caring about their pet’s welfare.

I wouldn’t do it, I’d get the expensive day care option.

This sounds fine, your dog will have the best day sniffing and running around the garden all day. It sounds like a secure garden and he will have shade, shelter, water and food. Your dog will be living the best life.

In the 90's my dogs only came in the house at night whether the door was open or not, they are dogs not humans and dont need to be treated like a baby. So dont let the negativity get to you you need to have your biopsy and im sure when you come home he will greet you with a big fuss.

Also I very much hope your biopsy goes well 💖

I would suggest filling a kong with mushed banana and peanut butter and freezing it - keeps dogs entertained for ages licking and chewing it! My mum did puppy minding for the Guide Dogs years ago and they suggested that as a good treat to leave! My mum also cooks up a meat mix with stock and freezes it in Kongs too, the dog knows it means it’s being left but is just excited to get its treat.

@Jojimoji we’ll have to agree to disagree then. I don’t think leaving a dog for 12 hours on its own is acceptable if you have alternatives (which the OP does but is for some reason choosing not to use them). And I said they don’t process time like humans (obviously 🙄) but they absolutely do have a perception of time lapse otherwise leaving them for days would surely be fine so long as they have enough food/water. It is recommended they aren’t left for more than 4 hours or so for good reason. Some dogs obviously can manage longer and owners will know their own dog best, but 12 hours is far too long for any dog, particularly when there are alternatives.

It sounds fine to me. He'll be in his own garden, with his own toys etc. around him. My girl is an indoor dog, but she'll spend hours out the back on a nice day, just lazing around, sunbathing and snoozing. He'll probably really enjoy it lol.

I hope your results are good by the way!

Honestly it depends on the dog - I have done that loads of times when I had dogs, some dogs are chill and will sleep or play with other pets others will lose their minds. It was the norm growing up that people would go to school/work and leave the dogs outside for a few hours - we used to just have the garage set up as a dog house.

My dad usually leaves his dogs home alone when he goes off to work all day as a vet, they keep each other company and also have a few cats they hang out with. I had one dog that I unwillingly adopted who had massive separation anxiety and would howl if left for more than an hour or two (even the grumpy cat was concerned and used to go home to cuddle him) so after a few months I had to rehome him with my dad who took him to work every day when he left the others at home. If your dog has separation anxiety you could try Borrow my Doggy or you could maybe check if neighbours have teens who want to earn a few bob by checking in on him at some stage in the day. If he is used to chilling in the garden and isn’t a velcro dog he will likely be fine. Make sure to leave out plenty of food! I’d suggest with the forecasted heat and dogs lack of sweat glands that perhaps as well as shade you could fill a doggy paddling pool with water or leave a cooling mat in the shade (my local Aldi has doggy paddling pools atm).

Of course it's fine, OP. I'd do this without hesitation. He'll have food, water, shade and somewhere comfy to sleep - he'll be fine. It's a dog, not a child. He'll probably sleep most of the day anyway.

If the dog is used to, and comfortable in the garden I think given the circs this is your best option. I have friends whose dogs are only ever kept out (more normal in rural areas).

Also to all those suggesting leaving the dog with a bone/pigs ear/chews, please be aware that dogs should only ever be given chews under supervision. They can and frequently do choke on them.

Hi Op,
you know your dog best , your set up sounds excellent the dog has all its needs met he will be fine. I have a Velcro Lurcher and when we are home she’s surgically attached to my husband , a couple of times a month she’s alone for 8/to 10 hours and is absolutely fine, we have cameras everywhere , she has access to an outside office lolls about on a sheepskin rug, takes a bit of sun has a snack and back to sleep again . Worse she’ll do is dig up a plant or two but she does that when we are home! She’s fine when we come back and I think it’s good for her. We adore our blue eyed girl but some dog owners get a bit hysterical about dogs. They treat them better than their kids.

look after yourself I hope your appointment goes favourably.

What happens if something goes wrong with your procedure and you can’t get home, or your brother gets stuck at work?

You can’t do this - pay for the expensive sitter or beg a favour from a neighbour.

My neighbour did this with her puppy & surprise surprise it escaped from the garden & would likely have got run over if we'd not intervened. There's also the small matter of your house insurance being invalid.
I'd pay for the expensive sitter - it's not worth the risk not to & you'd be able to focus on your appointment. Hooe it goes OK.

Don't do this, its advertising to the local ragamuffin that your house is empty and your "gaurd" dog is locked in the back garden.

Does anyone have a paper round near you ? Ask in uour local newsagents if they think the girl/ boy would be willing to pop in .
Or is there another sensible local teenage you trust ?

Failing that as long as you are 100 % sure your dog can't escape and won't get stressed I think it would be okvas a one off

I’d pay for the expensive person to pop in twice to take him out to the toilet and give him company. Even if it meant selling something to fund it.

Oh, I see!

I thought she meant she couldn't leave him in the garden ...

The OP mentions missing boosters "during the move" which implies that this is a new home, not a place where the dog grew up, and it is thus presumably an area the dog is not familiar with. If it's left for that long, it will find its way out of the garden and disappear, or end up being involved in an accident.
People here are being far too complacent.

Most people are suggesting booking the expensive sitter, not cancelling the biopsy.

Or trying Rover, borrow my doggy, local Facebook groups etc.

If the dog ends up with heatstroke she's going to feel awful. She has a solution, it's just pricey.

I would be concerned about wanting to keep a collar and tag on the dog in case they did get out, but then the danger of them getting trapped by it. I couldn't do it personally.

Maybe your vet would know someone who could help out?

Yes I do own dogs.

And I too am absolutely baffled by many of the responses on here. It's amazing that dogs survived as a species for thousands of years given that some people seem to think you can't take your eyes off little Rover for even a minute.

Only the OP knows her dog's temperament, but if it's a normal dog without any issues it really will be fine for one day in it's own back garden.

And dogs absolutely do NOT process time like humans.

Try Cinnamon Trust. They may have volunteers in your area able to help with temporary foster care

As a one off, it's fine.

Clearly, there are some people on here who would put a dog ahead of your own health and a biopsy.

Must be a full moon.

I am sorry you are going through this. I think you need a contingency plan in case you need to stay overnight or are delayed. There are some good suggestions above, I think I would review my options again.

Sounds reasonable to me as log as he is not likely to be yappy and disturb neighbours.
Do you have another plan if you have to stay overnight?
