0 City Dog: What to Know When Moving your Dog to the City

Before adopting our pups, I was always curious whether there was anything different about owning a dog in the city compared with where I grew up. We've been learning a lot as we go along, and trying to share what we know, and we just received this really interesting question:
What are some things a country or suburban dog can plan for when moving into the city?
Here are some things we've learned while having our dogs in the city.

Become a Walking Pro:

Living in the city can be challenging and our walks often feel like an obstacle course. From dodging food left on the ground--a disproportionate amount which seems to be chicken bones--, the sounds of the raging el train overhead, fireworks year-round, squirrels, rats, and feral cats, and crowded sidewalks filled with dogs and people.
Before moving to the city, we recommend beginning to take your dogs on regular daily walks around your neighborhood. This will give you a chance to begin working together in a comfortable and familiar environment, and you will also begin to understand your dog's triggers. Once you have identified your pup's distractions, you can also try changing up your walks so you can practice working in different settings. We've found it's helpful to treat every walk like a 'training walk' to make sure our dog is focused on us. We work on focus through regular check in's, and we wrote more about it here and here.

Start a Bathroom Routine:

With most of us living in multi-unit buildings, we actually need to prepare and take our dogs out for something as simple as a bathroom break. We developed a regular feeding routine, that has helped us with our bathroom routine. Our dogs eat twice a day: breakfast and dinner. We take them on their walks after they've eaten those meals (with a 20 minute digestion period). We don't leave water out, but they drink during their meals, and of course if it's hot outside they drink more and we take them outside directly afterwards. Besides the two food potty breaks we have a mid-day break and a before-bed break. We would recommend slowly transitioning your dog to a bathroom schedule before you move so it's more comfortable and less stressful later. We wrote more about the bathroom habits of city dogs, including what to do for late night emergencies, in our post here.

Finding Alternative Exercise:

Most city dogs don't have backyards, which can be a huge transition for dogs that are accustomed to having a lot of space and playing fetch. We have just become more strategic with the ways we tire out our dogs using a combination of physical and mental exercises.
We wrote about ways to get the most exercise on a shorter walk here.
And some mental stimulation to supplement or use during bad weather days in our post here. 
We also know a lot of city dogs that go to doggie daycare, go running with their people or hired dog runners, and walking groups. There are some dog parks in the city, though we don't like going to them for these reasons.

Be Considerate of Shared Wall Neighbors:

It could be confusing for dogs to move from a single-family home to a multi-unit building in the city. They might bark and react to the noises and sounds of other people constantly walking in the hallways. We are lucky our dogs have never been barkers, but we did have some visiting dogs that would bark at every strange sound they heard. I'm not sure if this is something they get used to, or if there can be some type of training (anyone?).

It's also important to be aware of any extra noises your dog could make and be respectful of the neighbors. It can be difficult to find dog-rentals in the city, so all of us dogowners should work to be respectful so people think well of owning dogs in apartments.
We wrote about some considerations when sharing walls with neighbors in our post here. 

Developing a Routine for the Humans:

I think the hardest transition might be getting the people accustomed to the routine. Every day we need to wake up a bit earlier to go on a morning walk, and we need to make sure we return in time to complete an evening walk. We also need to remain diligent about our training and be prepared to be outside in all types of weather.

Here are some ways we make our before-work walk quick and easy.
Here are some ways we prepare ourselves to walk in cold weather. And in the rain.

These are just our experiences, but I know there are a lot more things that we're missing.
