Another one here that takes their dog pretty much everywhere with them.
Ours is a 3 year old Jack Russell
There have been the odd longer mountain bike rides i've not taken here with me, but other than that if i'm out camping, hiking etc she comes along.
Took a bit of training to get her out of chasing stuff, but once we're away from cars and roads she's 99.9% off lead.
Doesn't harass sheep, ignores most other dogs, trained her to sniff out tortoise and she tends to chase grouse (what can i say i have to let her have some fun), other than that she rarely strays more than 10m from my side.
She sleeps in the tent, cause she's short haired she tends to feel the cold so i usually take a blanket or cover here with one of my coats or jumpers.
If it's really cold then i'll use her as a hot water bottle and she'll sleep in my sleeping bag.
Probably the biggest ball ache is her hairs, anyone that's had a JRT knowns what they're like for moulting.
It does make checking for ticks each night a LOT easier than other dogs i've had though, likewise just a wipe over with a damp cloth is usually enough to clean her off before she comes in the tent.
