You can certainly leave them together in their puppy-proofed space when you're gone all day, but they should be crated separately at night. You can crate them near each other, but this is the perfect time to start habituating them to not always being in close contact with their sibling.
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). If possible, dogs older than 6 months should not be left alone for longer than 4 hours at a time.
For the happiest dogs and the safest household, opposite sex dogs almost always do best together. Many same-sex combinations of dogs will fight, sometimes to the death. Those who work out a dominance order may not fare much better.
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.
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.
To keep your puppy healthy and happy while you're away, follow this general rule: Puppies younger than 6 months: Leave them alone for 2 hours max at a time. Puppies older than 6 months: Leave them alone for 4 hours max at a time.
To ensure that each puppy reaches his potential, everything needs to be done separately: walking, training, eating, and sleeping. If the pups are very young, sleeping together may be fine for a while, as long as they are getting enough one-on-one time with you, but before long they should sleep in their own crates.
Dogs are social animals and usually happier around other dogs, but a second dog will never be a substitute for inattentive, absent or too busy owners.
When dogs don't feel able to move away – which they may not when in physical contact with us – they may resort to telling us to back off in less desirable ways. Give dogs a way of “opting in” to social contact by using the “3-second rule” of petting. Pet for no more than three seconds, then stop.
What exactly is “littermate syndrome” and is it real? Littermate syndrome can occur when two puppies adopted from the same litter grow up together in the same home. In some cases, these sibling puppies form such a deep bond with each other that they fail to properly socialize with people and other dogs.
Typically, there should not be more than 1-2 hours between puppies although great variation exists. The delivery of an entire litter of puppies can take between 1 and 24 hours.
Many people are hesitant to adopt a second dog because they assume it will be twice the work and twice the money. But the truth is, owning two dogs doesn't have to be more work – in fact, it can often be easier. And as for the cost, it will cost more money than one but not twice the amount.
In dogdom, there's a turn of phrase called, "Second Dog Syndrome". This describes the process of adding another dog to the home quite well, but not necessarily in a positive light. As humans, we are bound to forget all of the time and effort it takes to raise a puppy right.
Many breeders recommend that your first dog be at least one-to-two-years old before you add a second to the family. If you have an old dog, they may not be physically able to play with or tolerate a pup.
Benefits of getting two puppies
Getting two puppies can help to ensure they always have company, even when you're not home. They can also play with one another when home alone which can help to reduce destructive behaviour. The other obvious benefit is that you'll get double the love and joy from two puppies.
It is a very poor decision to get two puppies from the same litter in almost all cases. Sometimes, people with extensive prior K9 knowledge may be able to handle the added stresses of getting two dogs from the same litter, but it is still generally not recommended.
Your new puppies should be crated separately and kept close enough for you to hear them at night if they need you. Train them individually: When training two puppies, the dogs should attend training classes separately.
Separation anxiety is a serious condition that creates high levels of stress for your puppy and often results in abnormal behaviour when left alone. Puppies may cry a little when you leave the house, but separation anxiety is usually explained by more extreme behaviours, such as: Destructive or disruptive behaviour.
Remember, dogs and especially puppies need to urinate often. As a guideline, new puppies up to 10 weeks old typically can't hold their bladder for more than an hour. Dogs between 10 to 12 weeks old can usually hold it for around two hours.
They enjoy friendly interactions with familiar humans or other animals and tend to avoid isolation. That being said, every dog is different has its own temperament and preferences. Some dogs prefer to live alone with their owners, while others prefer having another dog friend in the house.
