Changes in Coat & Skin

Regularly checking a puppy’s coat and skin is essential for identifying any issues. A healthy coat is a reflection of a puppy’s overall well-being. To ensure the optimal health of your puppy’s coat and skin, follow these guidelines:

  1. Inspect your puppy’s coat for any signs of patchiness, dryness, or dullness. Run your hands over their body, checking their fur for ticks, fleas, insects, or wounds.
  2. During playtime, scratches and scrapes can occur. It’s important to pay attention and address any cuts or injuries promptly.
  3. If you notice your puppy’s coat losing its shine or becoming patchy, it could indicate an underlying issue.

Signs of Coat and Skin Issues:

While some coat and skin issues can be minor and resolved with proper care, others may require veterinary attention. Look out for the following signs:

Puppies are typically enthusiastic eaters. They have boundless energy and a voracious appetite, always ready to gobble up their meals. However, there can be instances when a puppy’s appetite undergoes changes, leading to concerns for their health.

One common situation where a puppy may experience a temporary lapse in appetite is during big life changes, such as moving to a new home. The stress and unfamiliar surroundings can affect their eating habits. It is important to give the puppy time to adjust and offer them a calm and quiet space where they feel comfortable.

If a puppy is not eating as much as usual or refuses to eat at all, it could be a sign of an underlying issue. Vomiting in puppies is another worrisome symptom related to appetite changes. Persistent appetite problems and frequent vomiting are red flags that necessitate immediate veterinary attention.

The reasons behind appetite changes and vomiting in puppies can vary. It could indicate medical conditions such as gastrointestinal problems, infections, parasites, or even more serious illnesses. Veterinarians can perform a thorough examination and recommend appropriate tests to identify the underlying cause.

“A puppy’s appetite can be an important indicator of their overall health,” states Dr. Emily Collins, a renowned veterinarian with years of experience in puppy care. “If you notice any significant changes in their eating habits or frequent vomiting episodes, it is crucial to seek veterinary advice to rule out any potential health issues.”

Early detection and intervention are essential to ensure the well-being of your puppy. By addressing the underlying cause of appetite changes and vomiting, veterinarians can provide the necessary treatment and advice to help your puppy regain a healthy appetite and maintain optimal health.

Common Causes of Appetite Changes and Vomiting in Puppies

Gastrointestinal ProblemsConditions such as gastritis, gastroenteritis, or inflammatory bowel disease can cause appetite changes and vomiting in puppies.
InfectionsBacterial, viral, or parasitic infections can affect a puppy’s appetite and lead to vomiting.
Dietary IssuesFood allergies, sensitivities, or a sudden change in diet can disrupt a puppy’s appetite and trigger vomiting episodes.
Organ DysfunctionProblems with vital organs like the liver, kidneys, or pancreas can manifest as appetite changes and vomiting in puppies.
Intestinal BlockageIngestion of foreign objects can obstruct the digestive tract, leading to vomiting and a loss of appetite.
Motion SicknessPuppies can experience nausea and vomiting when traveling in cars or other modes of transportation.


Ear infections are a common problem in puppies, causing discomfort and distress. If you notice your puppy excessively scratching or rubbing their ears, shaking their head frequently, or detecting a foul odor from their ears, it could be a sign of an ear infection.

Puppies are more prone to ear infections caused by mites, while adult dogs typically experience infections due to bacterial or yeast growth. Ear infections can be quite uncomfortable and may lead to complications if left untreated.

If you suspect that your puppy has an ear infection, it is important to seek veterinary care for an examination and appropriate treatment. A veterinarian will be able to diagnose the infection and provide the necessary medications to alleviate the symptoms and promote healing.

Clear and healthy eyes are essential indicators of a puppy’s overall health. However, certain eye conditions can arise in puppies that require prompt veterinary attention. Look out for the following signs that may indicate an eye condition in your puppy:

  • Discharge from the puppy’s eyes
  • Excessive blinking or squinting
  • Pawing at the eyes

If you observe any of these symptoms, it is crucial to consult a veterinarian for a proper diagnosis and treatment. Early detection and timely intervention are vital for preserving your puppy’s vision and overall well-being.

Common eye conditions that can affect puppies include:

  1. Pink eye (conjunctivitis): Characterized by redness, swelling, and inflammation of the conjunctiva, pink eye can be caused by bacterial or viral infections. It may also result from allergies or irritants.
  2. Dry eye (keratoconjunctivitis sicca): In this condition, the puppy’s eyes do not produce enough tears, leading to dryness and discomfort. Dry eye can be caused by immune system disorders or as a side effect of certain medications.

A proper diagnosis from a qualified veterinarian and appropriate treatment are essential in managing these eye conditions and ensuring the long-term health of your puppy’s eyes.


Diarrhea is a common symptom in puppies and can be caused by various factors. It is important to understand the causes of diarrhea in puppies to ensure their health and well-being.

Some common causes of puppy diarrhea include:

  • Dietary Changes: Abrupt changes in a puppy’s diet can disrupt their digestive system and lead to diarrhea.
  • Bacterial or Viral Infections: Infections from bacteria or viruses can cause diarrhea in puppies.
  • Ingestion of Foreign Objects: Puppies are curious and may ingest objects that can irritate their digestive tract, leading to diarrhea.
  • Parasites: Parasites such as worms can cause diarrhea in puppies.
  • Stress: Stressful situations, such as changes in environment or routine, can trigger diarrhea in puppies.

Observing the consistency and frequency of a puppy’s stools is crucial in determining the severity of the diarrhea. While occasional loose stools may not be alarming, persistent or severe diarrhea should be addressed promptly.

If your puppy is experiencing persistent or severe diarrhea, it is highly recommended to seek guidance from a veterinarian. They can evaluate your puppy’s condition, determine the underlying cause, and provide appropriate treatment to alleviate the diarrhea.

Preventing Puppy Diarrhea:

While some cases of diarrhea in puppies may be difficult to prevent, there are measures you can take to reduce the risk:

  • Gradual Dietary Changes: When transitioning your puppy to a new diet, do it gradually over a few days to allow their digestive system to adjust.
  • Proper Hygiene: Practice good hygiene to prevent bacterial and viral infections in your puppy.
  • Puppy-Proofing: Keep hazardous objects out of your puppy’s reach to prevent them from ingesting anything that could cause diarrhea.
  • Regular Deworming: Follow a deworming schedule recommended by your veterinarian to prevent parasitic infections.
  • Reducing Stress: Minimize stressful situations for your puppy by providing a calm and secure environment.


Tracking a puppy’s weight is crucial for monitoring its overall health and detecting early signs of illness. Puppies should steadily gain weight and show a healthy appetite. Sudden weight loss and reduced interest in eating can indicate an underlying health issue. In such cases, it is important to consult a veterinarian for a thorough evaluation and appropriate intervention.

Importance of Puppy Weight Tracking

Monitoring a puppy’s weight is a valuable tool in assessing its overall health and development. Regular weight tracking allows breeders and puppy owners to identify any deviations from the expected growth pattern or potential weight loss, which can be indicative of underlying health problems.

“Tracking a puppy’s weight can provide valuable insights into its well-being and can help us identify any potential health issues early on.”

Expected Puppy Weight Gain

Puppies should experience consistent weight gain as they grow. The exact amount of weight gain may vary depending on the breed and individual puppy, but it is generally recommended to follow a weight chart specific to the breed for guidance. Most puppies double their birth weight within the first week and continue to gain weight steadily throughout their early months.

Sudden Weight Loss and Reduced Interest in Eating

If a puppy experiences sudden weight loss or shows reduced interest in eating, it can be a cause for concern. Weight loss in puppies can be caused by various factors, including medical conditions, stress, or nutritional deficiencies. If a puppy’s weight drops significantly or it displays a reluctance to eat, seeking veterinary advice is crucial for a proper diagnosis and intervention.

Consulting a Veterinarian

When faced with a puppy experiencing weight loss or reduced interest in eating, it is important to consult a veterinarian. A veterinary professional can perform a thorough evaluation, including physical examinations, blood tests, and dietary assessments, to identify the underlying cause and provide appropriate treatment options.


As breeders or puppy owners, it is essential to be familiar with a puppy’s regular behavior patterns in order to detect any deviations. Changes in a puppy’s behavior can often be a sign that something is wrong. If a puppy suddenly becomes quiet, nonreactive, or excessively vocal, it could be an indication of illness. It is important to seek veterinary advice if you observe such changes in your puppy’s behavior.

While every puppy has its own unique personality and may exhibit occasional odd behaviors, persistent or significant changes in behavior should not be ignored. These changes could be indicative of underlying health issues or discomfort that require prompt intervention.

Possible changes in puppy behavior that may signal illness:

  • Excessive barking or whining
  • Increase in aggression or irritability
  • Withdrawal or depression
  • Loss of appetite
  • Unusual sleep patterns
  • Restlessness or pacing
  • Excessive panting or drooling
  • Compulsive behaviors, such as excessive licking or chewing

It is important to note that changes in behavior may not always indicate sickness, as puppies can also exhibit behavioral changes due to environmental factors, such as stress or a change in routine. However, it is always better to err on the side of caution and consult with a veterinarian to rule out any potential health issues.

Remember, behavioral changes in puppies should not be dismissed. Prompt veterinary attention can help ensure early detection and appropriate treatment, leading to the best possible outcome for your puppy’s health and well-being.

Expert Tip:

“If you notice any significant changes in your puppy’s behavior, it’s important to document these changes and share them with your veterinarian. Providing specific details about the frequency, duration, and nature of the behavior can help your veterinarian make a more accurate diagnosis.”
