Getting a second one

Hi

About 3 months ago we rescued a 2 Year old corgi boy from the shelter. The family that surrendered him also had a girl and they grew up together.

At the time we adopted our first dog the girl wasn’t in the shelter but now she is and i’ve been thinking about adopting her so they could be together again.

Can anybody tell me how much of a diference does a second corgi make? Are they happier when theres two of them? Are they louder when theres two of them? We were really lucky that our boy is very quiet but im not sure we’ll get that lucky again.

Whats it like walking two dogs? Do you have them on a single leash that splits at the end or two separate leashes?

Any insight helps.

Thank you
