Ha! Ha! Just typed a response and before I posted realised CMOT’s list was the same as mine - only I had ankle wellies as well as crocs and a beanie with a headtorch in the front on mine as well. I also invested in thermal pjs and thick socks when we had a winter pup.
I have discovered spray mops since I had my last pup and this time around will be purchasing lots of extra pads for my mop, that I can use with puppy accident cleaner or some made up bio washing powder after the initial clean up, then sling on a boil wash.
Also second the slide on collar tags. My old boyhas had the same one for 14 years now and it’s still as good as new. I have a basic one on the d-ring as well though, because that’s where people tend to look first and he has a shaggy ruff which can hide his collar.
We use a crate for the car while they’re little, but having large breeds historically, we then move to a dog-guard and tailgate guard to give them more room. If you love your car, a boot liner is a good idea as an easier way of keeping it clean.
Socialisation - carry her anywhere and everywhere you normally go and dogs are allowed, so that she gets used to your lifestyle. Go at her pace and take her cue on when she’s had enough or if she’s happy, if she’s overwhelmed you can always retreat to the car. I have spent a fair amount of time sat in the boot of the car with pups, just watching the world go by. Keep interactions short and positive and with as many different types of people as you can manage.
Tempting as it can be to show pup off, personally I avoid school runs, as they get mobbed and it can be very distressing for young pups to be manhandled by a hundred tiny hands at once. I used to go and sit on a bench in a nearby park so mine could watch the schoolkids walking home and in the play area and get used to the squeals and yells etc, without being mobbed. That way you tend to get one or two people stopping to interact without the mob you get at the school gates.
