In a nutshell, no, you should not. You should let sleeping dogs lie, literally, and for good reasons too. You see, first, you can never really be 100 % sure of their reaction when you wake them up. This means that they might turn aggressive and cause injury. If not, they will be disoriented and worried since they will have no idea why you are waking them up.
This is more so if you startle them. When dogs are asleep, they may experience a dream, or a nightmare and whimper. When this happens, you might feel as if they are in distress and decide to wake up to save them, from whatever is going on in their sleep.
Dogs are like people in several ways, including their brain wave patterns. Just as humans can, dogs dream and the good news is that when they, they are likely dreaming about you, their owner. Apart from you, they may also be dreaming about their day at the park, chasing squirrels, or other breeds specific stuff, depending on the kind of dog you have. Of course, when dogs are having nightmares, it could be about something troubling they went through.
If you feel that they are having a nightmare, then you may wake them up, and we will share with you the best way how. First, how do you know whether they are simply dreaming about the new ball that you got them, or a nightmare? How do you know the difference? Usually, a dreaming dog will twitch, kick, and make quiet noises. On the other hand, a dog having a nightmare will cry, growl, and appear disturbed.
How Should You Wake Your Sleeping Dog?
Do not touch them
For most people, it is simply not possible to watch their pet suffering ion a nightmare. If you fall into that category and feel that you need to wake your dog, the first thing to keep in mind is that you should not touch them. Regardless of how loyal your pet is, if you wake them up by contact, you risk an aggressive reaction, and they could even bite you. It might take your dog a whole minute before they go from growling to their happy normal self so don’t touch them.
Use a gentle voice
To avoid startling your pet, even though you want to wake them up as soon as possible, you must use a gentle voice. If you use a strong or distressed voice, your pet will think something is wrong with you and wake up in protection mode. What you want to do is coax them awake, with a reassuring voice that you are fine and everything is okay.
Show them, love
Once your pet is awake, then it is okay to touch them. This is a good time to soothe them and shower them with some love in order to reassure them that things are okay. You can rub their head, or give them a comforting hug, or whatever works for the two of you.
Unless you have to, you should not wake up your dog when they sleep. The best things for your pet is to sleep until they have had enough and wake up at their own time.
