For me, Cruiser was taught these things right from the beginning and it's non negotiable. Especially that rets will grow really big and might have a hard time "unlearning" things when he gets older.
- Can the dog go on the furniture or not? Mine's allowed and I didn't get the expensive ones LOL
- Chewing should be always monitored. Unless you want to see worn out shoes, carpets, clothes etc every day.
- Also the barking should not be encouraged since they are the non barking types, which I really love about rets!
