15 Symptoms of Fading Puppy Syndrome Dog Owners Must Watch For

There’s nothing more heartbreaking than seeing a puppy struggle to survive. Fading Puppy Syndrome (FPS) is real, and it can take even the healthiest-looking pup down in a matter of days. It’s one of those things most new dog owners never expect but need to recognize quickly. You need to know these 15 signs to give your pup the fighting chance it deserves.

Lack of Weight Gain

Puppies are known for growing fast, but a puppy with Fading Puppy Syndrome might not gain weight as expected. If they aren’t keeping up with their littermates in size, that’s a major red flag. Regularly tracking their weight can help you catch this early. Ensure they are getting enough nutrition with vet-recommended supplements if necessary.

Constant Crying

All puppies make noise, but continuous crying can signal trouble. If your puppy is whimpering more than usual and can’t seem to settle down, it might be because they’re uncomfortable or in pain. Comfort them with gentle petting and keep them warm to help soothe their distress. And, keep an eye out for other signs along with crying. 

Low Body Temperature

Puppies can’t regulate their body temperature well, but a fading puppy will often feel colder than the rest of the litter. Check if your puppy seems unusually chilly to the touch, even when they’re with their siblings. They might need extra warmth and immediate attention. To give extra warmth, use a heating pad or warm water bottle covered in a cloth.

Lethargy

A healthy puppy is energetic and curious, but a fading one will appear weak and disinterested in their surroundings. If your puppy is too tired to play or even nurse, it’s time to get them checked. Early intervention is important here. In the meantime, gentle play and interaction should be encouraged to stimulate their energy levels.

Lack of Interest in Nursing

Puppies usually have a strong urge to nurse, but if your little one doesn’t seem interested in feeding, it could be a sign of fading. A puppy who refuses to nurse is not getting the energy they need to grow, quickly leading to further issues. Offer small, frequent feedings with a syringe or bottle to ensure they get enough nutrients.

Weak Suckling Reflex

Newborn puppies rely on nursing to get the nutrients they need, but a fading puppy might struggle with latching on. Try bottle-feeding with a specialized puppy formula to ensure they receive adequate nutrition. And, if you still notice your puppy having trouble feeding or not feeding at all, it’s one of the major signs to look out for.

Pale Gums

Healthy puppies should have nice pink gums, but a puppy with this condition might develop pale or grayish gums. This could be a sign that the puppy is not getting enough oxygen or that there’s an issue with its blood flow. Consult a veterinarian immediately to address potential underlying health issues.

Rapid Breathing

Watch your puppy’s breathing. If it seems faster than normal or labored, this could indicate respiratory distress, which often accompanies Fading Puppy Syndrome. Keep the puppy calm and seek vet assistance to manage breathing difficulties. Puppies should have a steady, calm breathing rhythm, so anything out of the ordinary should raise concern.

Diarrhea or Vomiting

Though puppies have sensitive stomachs, persistent diarrhea or vomiting can drain their strength fast. Fading puppies often suffer from digestive problems, which can lead to dehydration. Watch for abnormal stools or frequent vomiting. Provide electrolyte solutions to prevent dehydration and consult a vet for proper treatment.

Limp Body

If you pick up your puppy and they feel unusually limp or floppy, that’s a serious cause for concern. Gently massage their limbs to improve circulation and muscle tone. A fading puppy won’t have the muscle tone to hold themselves up properly, making them feel weaker than the rest of the litter. 

Weak Crying

Healthy puppies make strong, clear cries, but a fading puppy’s cries will sound weaker or quieter than usual. If you notice that your puppy’s vocalizations are softer, it’s another sign that they’re not thriving as they should. Monitor their condition closely and provide comfort to reduce stress.

Separation from Littermates

Sometimes a fading puppy will isolate themselves from their littermates. If they’re choosing to stay away or aren’t as active in the group, it could be because they’re too weak to keep up. Puppies are naturally social, so this behavior is a warning sign. You can encourage social interaction by placing them gently back with their littermates.

Difficulty Breathing

Breathing problems, especially labored or shallow breathing, can signal FPS. Watch for any unusual sounds like wheezing or gasping. Breathing issues should always be addressed quickly to prevent further complications. Ensure the puppy is in a well-ventilated area and seek immediate veterinary care.

Lack of Energy After Nursing

Puppies should perk up after nursing, but a fading puppy may remain tired and listless, even after feeding. If they aren’t showing signs of satisfaction after meals, it’s likely they aren’t getting enough nutrients. Provide additional feedings and monitor their energy levels closely. Offer smaller, more frequent meals to ensure they are getting enough nutrients throughout the day.

Unresponsive to Touch

Healthy puppies usually respond to petting or being picked up, but a fading puppy might not react at all. This lack of response can indicate that the puppy is too weak or sick to acknowledge human contact. If your puppy feels distant or disconnected, it’s time to act fast and seek veterinary advice immediately.
