I have indigo collar tags on my collars as you can fit way more info on them than on embroidered collars

Worth also adding a second tag with vet info on maybe too? For a lead, you could just use a bit of bailer twine on a trigger clip if needed?
Def add in a trip to get him chipped
Plenty of toys .. charity shops are great for cheap fluffies that you can stitch a bit before they end up in the bin rather than shelling out £ for dog specific ones, but just keep an eye on eyes/noses that can come off. REALLY recommend getting plenty of dried hooves, pizzles for teething, and I personally have dogs who love kongs and fleece tuggies - these can be soaked and frozen since Pastoral pups seem to turn into little sharks when teething. You can make your own tuggies but I have to admit I buy them as only a few £ - can do links if needed

For crates I swear by vetbed. Not the cheapest stuff to buy but fab fab stuff - liquid leaks through to underneath but the animal on top stays dry, and it washes and dries really quickly, is fairly (!) hard to chew up and lasts forever - I have bits in daily use from 2007 with my first dog that still looks good after being used by all 3.
