A second dog
Board and train before or after adding a second dog
A new dog learns your house partly from the dog already living in it. That makes the months before the second dog arrives the easiest time to fix the first dog's manners, and the weeks after a time to follow a plan rather than react to each new problem.
Before the newcomer
Train the first dog before the second arrives, while one dog and one set of cues is all you manage
Training is simplest with one dog. The AKC's advice for multi-dog homes is to work with one dog at a time while the others wait in another room or a crate, and before the newcomer comes, that is your whole household. A Foundation week, or Advanced for an adolescent that loses its cues outdoors, gives the first dog a place cue, a recall and calm household manners while nobody else is competing for the treats. The newcomer then arrives in a house with rules already running.
Pick the skills you will lean on most once there are two. A station, where the first dog lies down and stays while you deal with the puppy. Going into a crate or behind a gate on cue, since the AKC names a crate, an exercise pen and gates as the tools for separating dogs quickly. A leave-it. And a release word of its own: the AKC suggests a different release word for each dog, so settle the first dog's now and save another for the newcomer.
- Holds a station on a mat or cot while you are busy
- Goes into a crate or behind a gate on cue
- Leaves a dropped toy or treat when asked
- Has its own release word, different from the one the newcomer will get
Arrival weeks
In the arrival weeks, keep the first dog's routine whole and hold the first meeting on neutral ground
The AKC's guide to introducing a new dog says the first meeting should happen in a neutral place, not inside the established dog's home, and suggests walking the dogs in together afterward. It is just as firm about the resident: the older dog still needs plenty of one-on-one attention from the family. Keep its walks, meals and daycare days as they were. A first dog that already spends days at Dogtown hands the newcomer a few quiet hours at home to sleep.
Expect some grumbling. The AKC advises against reprimanding an adult dog for growling at a puppy, since the growl is how it says enough, as long as the puppy is not hurt; redirect or separate the puppy before things get out of hand. On Cape Ann, choose a quiet street or a friend's yard for the first meeting rather than the off-leash Gloucester Dog Park at Stage Fort. Each dog also needs its own license, and Gloucester lists $20 for a spayed or neutered dog plus a $2 processing fee, with higher fees announced for 2026.

Parallel programs
Once both dogs are home, run their training in parallel, never in the same session
Parallel means each dog has its own program during the same stretch of your household's life. A puppy starts with Tiny Tails Puppy School, for pups 8 to 16 weeks in blocks of 4, 6 or 8 weeks, or AKC S.T.A.R. Puppy, for puppies from 8 weeks to 6 months over 6 weeks and 12 sessions. An adult rescue gets time to decompress and then Calm & Connected, written for adolescents, new rescues and adult dogs. We confirm the minimum age for a board and train stay at the consult, so ask before planning one for a puppy.
Meanwhile the first dog keeps its skills paid. Dogtown Academy days, $89 for a full day or $69 for a half, include a training session with our trainer every day. If the first dog's manners slipped after the arrival, a board and train once the newcomer has settled is a sensible reset, and it gives you a week of one-to-one time with the newcomer at home. Whether both dogs can train during the same weeks, and how two dogs are priced, is settled at the consult.
| Household stage | First dog | Newcomer |
|---|---|---|
| Months before arrival | Foundation or Advanced, then daily practice | Not yet home |
| First weeks together | Same walks, meals and daycare days | Settling at home with gates, a crate and fixed meals |
| The newcomer is a puppy | Academy days or private sessions to hold its skills | Tiny Tails Puppy School or AKC S.T.A.R. Puppy |
| The newcomer is an adult rescue | Its usual routine, plus one-to-one time | Decompression, then Calm & Connected |
| Both settled | A refresher stay if skills slipped | Its own program, chosen at a consult |
Not for every home
If the two dogs are fighting, a stay for one of them is not the fix
Fights, injuries or guarding between the dogs need a different route: your vet first, to rule out pain, then a behavior plan run with you present. Polished Pup, 10 weeks and 20 sessions, is Dogtown's program for complex cases, resource guarding among them. The AVSAB's 2021 position statement says a trainer struggling to change a behavior should consult another reward-based trainer or refer to a veterinarian, a board-certified veterinary behaviorist or a certified applied animal behaviorist, and serious fights between housemates are that kind of case.
Sending the first dog away during the newcomer's first week is another mistake we would steer you from. It comes back to a house that changed without it, with a stranger already asleep in its spot. Let the newcomer settle for a few weeks with the first dog present, and choose the stay once you can see which skills actually slipped. If the first dog grows stiff, avoids rooms or growls more each day, tell us; those are signs to plan around, not to wait out.
- Fights, punctures or one dog hiding from the other
- Guarding of food, toys, beds or people
- Growling that increases week by week
- The first dog avoiding rooms it used to use
Updates and handover
Updates and the go-home lesson are where the second dog gets written into the plan
Tell us the newcomer's expected arrival date at the consult, with its age and where it is coming from, so the stay can practice the moments that will matter: a station held while another dog moves nearby, a calm wait at the door with a second dog behind it. Daily updates should report how the first dog held its station around a steady dog. The format of the updates, with or without photos and video, is settled at booking.
Foundation ends with one go-home lesson and Advanced with two coaching lessons. If the newcomer arrives between them, Advanced's second lesson is the natural time to ask how to add a puppy behind a gate while the first dog works. Both dogs need the free evaluation, on a weekday between 6:30 and 9:30 AM, before daycare, Academy or an overnight stay, with Rabies, DHPP and Bordetella on file. Our two-dog household guide covers daycare, walks and grooming for the pair.
