@Inbedbynine Boys... castration is a much simpler procedure than spaying a bitch. And chemical castration is also available if you don't want a general anaesthetic or have a splendid healthy specimen of a vulnerable breed and breeding in the future might be an option. However when they widdle they aim high so walls etc in your garden are likely to get smelly.
Girls, slightly less likely to wander. If you prefer not to spay you will have to watch her like a hawk twice a year for about three weeks, and put up with little drops of blood.
Things that are worth the money. Vetbed. Washes like a dream and soaks up all the muck from muddy puddles. Good sturdy car transport system. You can get shaped crates for the car boot, make sure they have a proper solid base - I had a lovely one except that the base was fabric and the dogs had it in tatters within days. I replaced it with one taken out of an old rectangular crate. Alternatively a harness and a leash with a fitting to slot into a seat belt catch. It is an offence to drive around with an unsecured dog now.
For chewing, antler. It lasts far longer than anything else and seems to continue to smell attractive and interesting for ever.
For throwing/catching/chasing, balls that are too big to swallow and can't be destroyed and partially eaten. And rubber flying rings that won't shatter into sharp bits.
Water, a very heavy cylindrical bowl, less likely to be tipped over. Food, stainless steel is easy to wash.
Puppy pads may be useful in the early days, but beware of getting trapped into DPup thinking they're the right place to go rather than for emergency use only.
And book onto a puppy socialisation/training class. You'll get to know other local dog people and learn useful stuff like best local vets, good local walk routes and parking places etc.
