How to Train a Rescue Dog: Shelter Dog Training

All dogs deserve an adjustment period: time to relax and decompress when they undergo a huge environmental change. And becoming part of a new household is quite the change! Dogs who have lived in shelters deserve extra consideration as they adjust to home life after living in a very stimulating (and sometimes frightening) environment. The sights, sounds, smells, routines, and general chaos of a shelter can take a toll on a rescue dog, especially if they were housed there for a lengthy period (or during a critical time in their own development, like part of young puppyhood).

Plus sometimes much of a shelter dog’s past life is unknown, including a history of abuse or history of neglect. While these things aren't the most common previous experiences—most furry friends in the rescue world are surrendered due to circumstances like their guardians moving or having financial struggles, rather than outright abandonment or harm—they are possibilities to keep in mind as you try to set up a calm environment for your new dog.

What that means for you: Anyone adopting a shelter dog, especially first-time dog owners, should be prepared to ask lots of questions. If you need help before you bring a new dog home from the shelter, talk to a credentialed professional trainer who utilizes modern, humane training methods to prepare you for basic obedience training—and work you through any behavior obstacles you may face when your dog comes home.

When introduced to their home with care and compassion, shelter dogs can make some of the best family members! And saving a life is one of the most rewarding experiences.

Before you bring your dog home

Talk to the shelter staff about the dog you’d like to bring home to see if they are a good fit for the lifestyle you (and your family) live. Some important questions to consider:

Has the dog you're interested in shown any signs of fear or aggression?

How is your potential new family member with bathing and grooming activities?

How do they feel about putting on gear (collar, harness, etc.)?

What about their reaction to body handling?

How do they feel about getting in/out and riding in a car?

What kind of activities do they enjoy?

How energetic are they?

Do they have protect/guard resources (food, toys, spaces, etc.)?

Do they have any injuries or health conditions?

Are they house trained? What about crate trained?

Has the dog met children and how did they react?

How does the dog do with other dogs and other animals?

Does the shelter anticipate any specific training issues? (If so, this doesn't have to be an automatic dealbreaker! Behavioral cases—like particularly fearful rescue dogs or those who display unwanted behaviors in a shelter environment—can often become excellent companions. Adopters just need to be prepared for more work, and ready to work with a positive reinforcement trainer from the get go.)

Some shelter dogs are brought into a foster program. If this is the case, the foster should be able to answer most of these questions. This information is useful for you to transition a dog into your home and as you begin working with a professional trainer.

Remember the importance of socialization

Socialization in dogs refers to being exposed to new stimuli and ideally making positive associations—or at least feeling neutral about a variety of places, people, other animals, and things.

Many shelter dogs lack socialization through no fault of their own. The window for initial puppy socialization closes between 16 and 20 weeks of age—these periods of time are when having positive experiences with as many sights, sounds, smells, and sensations is the most important. Adopting an adult dog means the window for critical socialization has closed for them. While providing positive experiences that help build an older puppy or adult dog’s confidence is possible, this is no longer considered socialization. Unless the information has been provided when the dog is surrendered, you are unlikely to have information on life with their previous owner, or how a shelter dog was socialized as a puppy.

Not all dogs have been socialized to children. This is a very important consideration before you decide to adopt a shelter dog–the last thing you want is to put a child at risk. Talk to the staff about the best way to introduce children to a new dog, or contact a trainer to help guide you through the slow introduction process to ensure everyone, furry and human, is safe.

Fearfulness, anxiety, and related behavior issues require counterconditioning and desensitization (and possibly medication) before the dog is able to learn. In other words, training by itself does not fix behavior issues. An experienced trainer, behavior consultant, and/or Veterinary Behaviorist may be necessary. It’s worth noting here that not all behavior issues are caused by trauma. Genetics, lack of proper socialization, health issues, and learning history are all factors. A puppy is not a blank slate, and these same factors apply to their development. Dogs experience stress, and those experiences affect their ability to learn.

training a shelter dog

Expect an adjustment period

You may read about the 3-3-3 rule (sometimes stylized as the 3/3/3 rule) for shelter dogs. It goes like this:

Three days to rest and decompress

Three weeks to settle in and establish a routine

Three months to become fully integrated into your home

This is a general guideline, and some dogs may take longer to feel comfortable. Remember that shelter environments can be stressful for dogs. They may simply need space and time to rest during their first few days home!

Right away: Give your dog space to decompress

Provide comfortable, separate-but-accessible spaces for your new dog to enjoy quiet time away from other pets using gates, pens, crates, or separate rooms. Introductions to other pets should happen slowly over a period of weeks. You might make use of crate time, larger x-pens, or dog-proofed separate rooms during your new family member's initial adjustment.

Decompression refers to spending time away from frightening or triggering stimuli and focusing on rest and relaxation. The main focus of decompression is reducing baseline stress. Make sure your new dog’s needs are being met as far as nutrition and rest, or any medical care they may require. The first few weeks after your shelter dog comes home should be very low key. Avoid busy places (dog parks, cafe patios, friends’ houses, gatherings). It is best to limit human interactions to immediate family if possible.

Go at your dog’s pace, especially if your shelter dog is fearful. Step into your dog’s shoes. Everything in your shelter dog’s world is new when they come home with you. Try to imagine how overwhelming it might be for them. Be patient and adjust your expectations so you can help your dog in each new situation they encounter. Provide lots of positive rewards along the way!

Embrace enrichment

Provide regular enrichment such as food puzzle toys or unhurried time in safe nature environments as part of your dog’s daily routine. (This may include outdoor time in a private space like a Sniffspot.)

Get on a schedule

It doesn’t have to be perfectly timed or rigid—but providing your newly adopted dog with a predictable daily routine may help them settle in faster. If activities and social interactions are consistent and predictable, they may have an easier time.

Schedules are especially important for house training. Take your new family pet outside at regular intervals: after meal times, after indoor exercise, and after naps are a great place to start.

Schedules can also help with crate training, if that's something you want to pursue with your rescue dog. (When used properly, crates can serve as important safe spaces to help shelter pups handle family life!) You can teach your new addition that there is a different between exciting time (for play and social interaction) and rest time (settling in a calm space).

Find out what makes your new dog tick

While your dog is adjusting to your home, start reinforcing behaviors that you appreciate. This is not the time to think about "obedience" in a traditional basic-cue (like sit, down, come, etc) sense. Rather, it's the time to keep reasonable expectations—and set the foundation you can build on later!

Start rewards-based training at home

The easiest way to begin rewards-based training methods with your dog is to keep small containers of treats around the house. When you spot them doing something great, say “yes,” toss them a treat. By providing a treat, you are increasing the likelihood that the behavior will be repeated. This is how positive reinforcement works.

Kathy Sdao’s See Mark And Reward Training (SMART) is the best example of this simple type of training. Eye contact, responding to their name, resting in one of the comfy spots you’ve made for them (a crate or a bed), are all great behaviors to reinforce.

Once they’ve had some time to get used to your household, figure out what your dog likes to do. What kind of toys do they like? What’s their play style? What is interesting to them if you’re going on a walk? Provide your dog with activities they enjoy and observe their behavior afterward. What activities help them settle and rest? When do they seem most engaged with you? Keep track of what kind of treats they like the best for when you begin training in earnest.

Find a class

If your dog is not fearful of other dogs or people, a group training class, such as puppy or introductory new dog class, is a great way to learn the basics. A good rewards-based/positive reinforcement trainer will help you understand how your dog learns and how best to teach them some skills that are useful for a life in a human household and world. This may include learning to use a clicker.

Group classes are as much (if not more) for the human end of the leash as they are for the canine end. You may be assigned homework. Group classes are generally structured so each session builds on the next, so remember to do your homework. Although the class may be called “obedience,” the purpose of group classes with a humane, positive reinforcement based trainer is to strengthen the bond between human and dog. You’re in it together! You’ll learn cues (basic commands) like sit, down, stay, begin the journey of walking together with a leash, and other basic obedience-related behaviors. If a formal obedience class is your thing, there are many that use rewards-based training methods.

Once you learn the basics, your dog may enjoy a tricks class or other more advanced training program. Most training facilities offer a variety of classes, so if you find a trainer or facility you like, see what else your dog might enjoy. Any dog can learn new skills or cool tricks as long as they are having a good time!

Find a trainer

If one-on-one training works better for your dog or your schedule, seek out a credentialed trainer who utilizes modern, science-backed, humane training methods. Whether they train in a facility or in your home, private training sessions are also great for learning basic skills. Private lessons also allow you to focus on specific skills or do some troubleshooting that you couldn’t do in a group class. Your trainer will develop an individualized training plan for you. If your dog displays challenging behaviors, private lessons are best.

Small, frequent sessions are better

Whether you’re working in a group class or privately with a trainer, keep your at-home training sessions short and positive. Short, frequent training sessions help to prevent your dog from getting frustrated or failing at an activity. If this happens, make the exercise easier by breaking it down into smaller steps, or going back to something you know they are already good at. Short, frequent sessions are the best way to work on any homework you are assigned by your trainer(s) from class or private sessions.

Use small, soft, smelly treats that are appealing to your dog and easy to chew. You’ll go through a lot of them during your training sessions. Dry treats require more chewing and often don’t work well for class, but this is where finding out what treats your dog prefers comes in handy.

Get professional help if you need it

Shelter life is hard, and so much is not known about dogs who end up in them. Whether they were found as strays or surrendered, there is a lot of background information on a shelter dog that you simply cannot know. If you adopt a dog from a shelter and they struggle with behavioral issues related to fear or anxiety, or display aggressive behaviors, seek professional help from an experienced trainer. They may recommend a behavior consultant or Veterinary Behaviorist. A team, including a veterinarian, is necessary for behavior cases. It takes a village! Please note that credentialed trainers, behavior consultants, and Veterinary Behaviorists utilize science-based methods. The American College of Veterinary Behaviorists and American Veterinary Society of Animal Behavior recommend against the use of aversive equipment such as choke, prong, and shock collars.

Final Thoughts

Dogs that find themselves in a shelter are amazing, resilient, complex, fabulous dogs. When they first come home, they need and deserve time to rest in comfortable spaces that are just for them, and make choices on how and when they interact with family members. Let them come out of their shell at their own pace, provide positive reinforcement for behaviors that you appreciate, and get to know them before you and your new friend begin your official training journey together.

It is worth noting that just because a dog exhibits nervous or fearful behaviors when they first come home, they may not have a behavior issue. You should, however, monitor the dog’s body language closely. This is very important information for an experienced dog trainer, behavior consultant, Veterinarian, or Veterinary Behaviorist should you need additional help.

Dogs, like humans, enjoy lifelong learning. So don’t just stop with the basics. Learn and grow together!
