Good morning everyone 
I am feeling quite perky as Rudy is starting to fall into shape
Right we seem to have a lot of questions-
First of all wats and assumpta, do you have a basic puppy book? You will need something have a look on Amazon if not.
wats is this your first dog? New puppies are a nightmare, but so worth it in the end. Toilet training takes endless patience you must take him to where you want him to go, every time he wakes up, every time he has played, everytime he has eaten, every hour or so for good measure and always straight away if you see him sniffing or circling.
It will be hard with the kids initially, clicker training would help, have you considered that?
assumpta basic comands, you really need a book or classes to make sure you are teaching coreectly if you haven't done it before. Make sure it is a method that teaches positive reinforcement rather than old-fashioned compulsion. For weeing and pooing I say 'go wee' and 'go poo' lots of others use 'be quick' or 'get busy', the dog has no idea what you are saying so choose any command you like. try not to use something the puppy will hear in other situations, I am forever saying the the dc's 'go on then, be quick', this would obviously be disatarous
.
Ants arn't a problem though slugs and snails are, kid I'm not sure if you are aware of this? They carry lungworm which if untreated is very dangerous and dogs must be prevented from eating them. Make sure the wormer you are using protects against lung worm as not all do.
