    they do and you will. Any heating applience will consume a lot of amps, if it does not it will not heat. If you are on hookup use a mains blanket, better still just add an extra high tog quilt.

    Little dogs are cheaper to keep, and often more faithful.

    Depends waht you call batteries, a factory built european motorhome might have a single 85 or 110 ah battery, but someone who camps off grid a lot might have 4 or 5 110 amp hour batteries.

    also different lecky blankets pull different powers, some have thermostats, some dont.

    i know someone in america who suffers from some freezing feet problem, and he uses a 12 volt blanket, his pulls 4 amps and is on a thermostat, his battery bank is around 500AH, so that's absolutely nothing to it,

    Just depends what you want to do with the blanket, just warming a cold bed up before getting in, fine, (tho i must admit a dog is a lot better at that... a collie sized dog puts out around 100 watts of heat apparantly)

    but if you wanted to use the blanket instead of heating, and keep it on all night, you better have a big battery bank and a way to recharge it fast the next day.

    A 48 watt electric blankets for 8 hours will take around 32 A/H out of the battery bank.

    Because batteries aren't 100% efficient, it means about 35 A/H to recharge it.
    More with older batteries.

    That's a fair bit of recharging each day; even that 500 A/H battery bank will struggle to last a week without charging unless the owner is happy to go below 50% capacity..

    Anyhow, a 35 A/H withdrawal from the battery isn't too bad if one has 200 A/H worth of storage batteries and at least an hours driving the next day.
    A longer drive would be better as getting the last 20% into a battery takes a fair time.

    Perhaps a wind generator and a windycampsite would do the business if one isn't going to move a fair distance the next day.

    Seems a lot of bother compared with a couple of hot water bottles, bedsocks and some fleecy jim-jams, if the small dog is out.
