Adopting a 2 year old dog tomorrow. Any tips? - eviltoast

My wife and I have always wanted to have a dog and out of an interesting turn of events, we have the opportunity to adopt a 2 year old dog that a family friend cannot take care of anymore (they developed an illness that radically saps their energy).

Super excited but a little worried about making sure the doggo is taken care of properly. We’ll have to drive him back in our car for 3h30 and we have an old overly-affectionate cat.

What do people think? Any tips? Relevant stories? Give me your thoughts and have an awesome day!🙂
