According to the American Kennel Club, puppies younger than 10 weeks cannot be left alone for more than an hour. From 3-6 months, they should not be left longer than their age in months (for example, 3-month-old puppies cannot be alone for longer than 3 hours).
Young puppies under six months shouldn't really be left alone for more than two hours. And it's a good idea to build up the time they spend alone gradually to prevent separation anxiety from setting in. When you do leave your puppy alone, it's a good idea to crate train them, or leave them in a puppy-proofed room.
Puppies are prone to it because they're social animals that crave your attention, and it takes time to teach them how to be alone. So teaching them how to be alone for periods of time is a very important step in your puppy's training and growing phase!
Do puppies grow out of separation anxiety? Unfortunately, puppies don't just grow out of separation anxiety. If you leave it untreated, it will likely just get worse, and it certainly won't get any better! However, thankfully, it's not too difficult to treat and just takes a little TLC and training.
You should never leave a puppy to cry when they are in need of the basics, or this can cause difficulties with training later. Your puppy may cry when they are left alone, perhaps if you're elsewhere in the home or asleep.
If you work more than eight hours a day, or if you'd just like your dog to go outside when you're gone, you have a couple of options: taking your dog to doggy daycare, or asking a neighbor or a petsitter/dogwalker (or even a personal assistant) to let your dog out and/or take him for a walk.
Different dog breeds have different energy levels and rates of growth; the growth plates in their joints close at different ages. But do schedule play and exercise time into your puppy's day: a walk around the neighborhood, playing with toys, and time spent bonding go a long way toward expending energy.
During a puppy's first year they really don't like to be left alone for long – even popping into the next room in the early weeks can leave them anxiously wondering where you've gone. This means that puppies can feel vulnerable at night if they are left on their own. They cry because they need company and comfort.
Leave your puppy alone in his crate or puppy playroom for at least 30 minutes to an hour each day at first. Gradually increase that length of time to up to two hours for a pup three months and younger, or up to four hours for a pup from three to six months old.
Their young bodies and brains are still developing, and leaving them alone for too long can lead to behavioral issues and conditions like separation anxiety. No dog should be left alone for a full 8-hour workday.
If not family, you could ask a helpful neighbor or even hire some help in the form of a dog sitter. A few dog owners will use a 'doggy day care' center for their puppy before picking them up on their way home from work.
Consider doggy daycare
If your dogs don't do well at home alone or you work long hours, doggy daycare is an excellent option. Even if it's just a few times a week, daycare can make a huge difference — your pup can socialize with other dogs, play, and get the exercise they need.
Modified 5-Minute Rule
One of the most popular answers to how long a puppy should exercise per day is 5 minutes for every month of age, twice a day. This means an two-month-old puppy should get 10 minutes of exercise twice a day. This is a good starting point, but not all dogs are the same.
Growth stage: By one year. By the time they're one year old, dogs should be making progress in learning of all the polite behaviors they will need for the rest of their lives.
It is not uncommon for a puppy to defecate 5-6 times per day. Some will eliminate even more frequently. The good news is that the pace of pooping will slow down as the dog matures. Although a 2-week-old puppy may defecate at every feeding, by 12 weeks, they may be down to only 4 times per day.
Gradually increase the time you leave your puppy alone in the house to about half an hour. Depending on your puppy, this can take a few days or longer but it's important you move at their pace. If your puppy shows any sign of worry, go back to leaving them for a time period where they were last comfortable.
Tips to help prevent separation anxiety
Constant attention when you are home makes it harder for him when you leave. Schedule alone time for your dog each day while you go for a walk, pick up groceries, take a short drive, or take a shower.
Teaching Alone Time
Begin by closing your puppy in the confinement area with a chew toy or other constructive activity, then quietly walk out of the room. Return immediately and reward them with praise and a treat. Repeat the process, slowly increasing how long you're away each time.
