Large dog. Older, arthritic and much beloved. Want to travel safely with her in the heatwave on a LONG trip.
I have to drive alone from Cornwall to south Scotland on Wednesday, non-negotiable as to why or when tbh. Only option is really to cancel my attendance (family event) which I really don't want to do as it's to see people I haven't seen in years and won't again for many more. It's about 10 hours door to door including three usual breaks.
I have a large estate car, dog travels in the boot with a very thick memory foam bed.
I have air con, the rear windows and back screen are tinted. I've got a rear window stick on screen and back window sleeves coming tomorrow as well as a reflective windscreen cover to place in the car when we're not in it. I also have a tailgate vent lock so can prop the boot open securely when we're not moving.
Plan is to leave about 6am, with the usual breaks at Gloucester services, somewhere around Stoke and then Tebay.
In the past, I've been able to leave her in the car for 10mins while I run in for a pee, but obviously in this heat that's a huge risk I'm not comfortable with.
At Glos and Tebay I can probably sprint with her into a family loo (I'll await the horrified outcry of me using these facilities without a child) and back to the car plus take her to somewhere shaded for a pee and a leg stretch. We've blagged it before...
Does anyone have any experience of doing the same at random other services?
Will be packing insane amounts of water (in case of a motorway closure / diversion etc), snacks, her food etc, might take my sun umbrella just in case as well. Maybe I should pack her cool mat? Her cooling collar?
Am I overthinking? Missing something? Any advice?!
