Thanks for the ideas! I had forgotten the collar training totally - as well as walking in leash nicely. Fortunately I have some training collars at home, before my order of measure made sighthound leather collars will arrive (at age of 8 weeks).
We have now -20 Celsius and 1 meter snow in South-Finland, so it is impossible to start potty training in the garden 😉
More ideas are welcome!
