redwinetime : I’ll be the odd one out and say, in my experience (and this is just me!), I think 2 dogs is double the work if the 2nd one is a puppy. I’m not sure how it is with 2 older dogs, but I would NEVER do a 2nd dog that is a puppy again.
One is older, so the younger one needs to be crate trained while the older one free roams. One free feeds but the puppy will eat anything in sight so they are fed separately. One goes to scent training and agility, the other one is going to puppy kindergarten. Training daily for each dog is different.
I disagree with another commenter that you don’t need to walk the dogs anymore because they play together. Walks are more than physical exercise. They provide mental, physical, and ongoing socialization. The pups might love each other and get tired out from play, but they should be constantly interacting with outside things too or you can end up with “the grumpy old dog” type. For the first year of the 2nd pup, we walked our dogs separately. Yup, separately, meaning double the walks because we needed to train the younger one leash manners and the older one would get super frustrated, understandably.
Do you ever travel (plane or road trips) with your dog? Travelling with one dog was a little stressful, packing for 2 is not fun. Then there are logistical issues like I fly with my pup, can take him out and go through TSA. I can’t do that with 2 pups, so my SO has to be there or board them (which I really don’t like especially with the one that has SA).
Lastly, if you’re thinking of getting a 2nd dog because of separation anxiety (that’s one reason why we did), I have to say that adding a 2nd pup doesn’t guarantee separation anxiety goes away. Our older one still freaks out and howls even though the younger one is there. We learned the hard way, unfortunately.
All that said, I might care too much about dog training… so maybe I’m just anal about the amount of work you really have to do.
EDIT: I wanted to add that the general suggestion is getting a 2nd dog once the first dog is over 2 years old so they are almost or fully mature. A dog changes a lot in the first 2 years. Our older one, even after so much training, only got snarky, barky, SA after he was 1.5 years old. I’d wait to see how your pupper does once he’s over his teen years.
