It is completely instinctive, and your puppy knows how to do it from the moment they are born. The reason why is very simple &#8211; they need to be able to suckle in order to nurse from their mom, and survive!<\/p>\n\n\n\n<p><strong>If you&#8217;d like to know more about how puppies develop from birth onwards, check out <a href=\"https:\/\/www.thelabradorsite.com\/puppy-development\/\">Pippa&#8217;s lovely guide to puppy growth and development<\/a><\/strong><a href=\"https:\/\/www.thelabradorsite.com\/puppy-development\/\">. <\/a><\/p>\n\n\n\n<p>The fact that suckling is such a deeply hardwired behavior is one reason why dogs might continue to do it long after <a href=\"https:\/\/www.thelabradorsite.com\/feeding-your-labrador-puppy\/\">they have weaned<\/a>. Some dogs move on to sucking their blankets <a href=\"https:\/\/www.thelabradorsite.com\/best-puppy-toys\/\">and toys<\/a> while they are awake, whilst others only ever suckle in their sleep.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" width=\"600\" height=\"519\" src=\"https:\/\/www.thelabradorsite.com\/wp-content\/uploads\/2024\/02\/puppy-sleeping.jpg\" alt=\"photo of a yellow labrador puppy asleep on a rug with her grey teddy bear\" class=\"wp-image-40215\" srcset=\"https:\/\/www.thelabradorsite.com\/wp-content\/uploads\/2024\/02\/puppy-sleeping.jpg 600w, https:\/\/www.thelabradorsite.com\/wp-content\/uploads\/2024\/02\/puppy-sleeping-300x260.jpg 300w, https:\/\/www.thelabradorsite.com\/wp-content\/uploads\/2024\/02\/puppy-sleeping-534x462.jpg 534w, https:\/\/www.thelabradorsite.com\/wp-content\/uploads\/2024\/02\/puppy-sleeping-486x420.jpg 486w\" sizes=\"(max-width: 600px) 100vw, 600px\" \/><figcaption class=\"wp-element-caption\"><em><strong>Sleep suckling, like cuddling up to a toy, may be soothing to young puppies<\/strong><\/em><\/figcaption><\/figure><\/div>\n\n\n<p><a name=\"why\"><\/a>Let\u2019s look closer now at all the possible reasons why they do it.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"reasons\">1. They\u2019re Hungry<\/h2>\n\n\n\n<p>The first reason puppies may suckle in their sleep, whilst they\u2019re still nursing from their mom, is because they\u2019re getting hungry again. They\u2019re likely to wake up soon, and begin rooting &#8211; search for a nipple to feed from.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">2. To Self-Soothe<\/h2>\n\n\n\n<p>Suckling is such a deeply ingrained behavior that it doesn\u2019t need conscious thought. And it has lots of positive associations &#8211; of being close to mom, of feeling safe and secure in her care, and of getting a meal!<\/p>\n\n\n\n<p>So for some dogs, suckling in their sleep might be a self-soothing reflex.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">3. They\u2019re Dreaming About Suckling<\/h2>\n\n\n\n<p>Just like us, dogs experience dream sequences which mimic their waking lives. And whilst most of it only takes place in their head, occasionally they perform some of the sounds and movements which go with their dream. So dogs who dream about suckling might act out motions suckling whilst asleep.<\/p>\n\n\n\n<p>This is most likely to be the case in puppies who are still nursing, or only recently weaned. Or older dogs who still like to suck their toys and blankets whilst awake.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">4. It\u2019s A Symptom Of An Underlying Condition<\/h2>\n\n\n\n<p>Occasionally suckling in their sleep might be a sign of an underlying health condition. Tonsilitis, for example, causes dogs to need to swallow more often. Which may look like a suckling motion whilst they\u2019re asleep.<\/p>\n\n\n\n<p>Dogs with obstructed airways might also sleep with their tongue hanging out to allow more airflow, and make similar \u201cwet\u201d noises to a dogs who is sleep suckling. Obstructed airways are a common problem of flat faced breeds, such as Pugs and French Bulldogs.<\/p>\n\n\n\n<p>Finally, dogs who use sucking behaviors to self soothe might start doing them more often if they are feeling anxious about something &#8211; a new home, or a new dog in the house for example.<\/p>\n\n\n\n<p><a name=\"should\"><\/a>And this can spill over into sleep sucking too.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What To Do About A Dog Who Suckles In Their Sleep<\/h2>\n\n\n\n<p>In most cases, suckling in their sleep doesn\u2019t do dogs any harm. If you share a bedroom and the noise is bothering you, it might be time to move them into a different room at night time, or invest in some ear plugs!<\/p>\n\n\n\n<p>Dogs who use sucking behavior to self soothe might enjoy having some plush toys of their own to suckle at bed times. Make sure you choose ones without any small plastic parts that can come loose. If your dog has started suckling in their sleep without any history of doing it, or they start suckling much more than usual, or they have any other signs of illness, consult their vet.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Why Do Dogs Suckle In Their Sleep &#8211; Summary<\/h2>\n\n\n\n<p>Suckling in their sleep is a fairly common behavior in dogs, and it is rarely problematic in Labs. We can use clues like a dog\u2019s age and waking habits to guess why they might be suckling in their sleep.<\/p>\n\n\n\n<p>But there\u2019s always an element of guesswork, which means we can\u2019t be 100% sure.
