Pretty obvious this was inspired by another thread.
How soon would you add another dog after one left you? If the dog passed? Ran away? Was rehomed? Are any of these different or do you have a period of time you just need between dogs?
For me if Bandit passed on right now I would not get another for years. I am in no place to add anything new. I love my dog the only reason I have a dog currently is because he was there before, I can make it work and I love him with all my heart. If he were to die I would not be very responsible to add another.
We are all different. So, explain. Would you get a new one right away or wait?
