For your own sake, and your dog sake, I would say hold off getting another dog until Toby is well obedient trained. at least until his 1st birthday. Dogs can be well behave outside the home just like our children are always so good in other people's house. The circle runs, known as zoomies, you have in the house is likely to be multiplied by 2 with another young dog. Furthermore, # 2 could very well be enven more energetic than Toby...
