Get a house sitter. For example someone from Happy House Sitters
For a long sit like that, you would like have A LOT of offers from very experienced people who have police checks and lots of experience with dogs. You put an ad up for free and get to scroll through all of the applicants and meet them and discuss the arrangement that you want (ie. division of costs and car etc). The more professional house/dog sitters will have their own contract or form so you can agree of things like emergency vet visits (eg. if you're not contactable) and they'll likely send you lots of photo updates through WhatsApp.
Another option is Find a Dog Minder although I think it's much more common for shorter stays.
I have used both options and have had great success.
