How to Respond to Drastic Changes in Your Pet’s Behavior?

Every pet owner knows that pets are just like family members, and just like human family members, their behavior can sometimes take unexpected turns. It’s important to understand the reasons behind these behavioral changes, whether due to physical health issues, environmental changes, or emotional factors.

Identifying Drastic Changes in Pet’s Behavior

Drastic changes in your pet’s behavior can sometimes be concerning. Its pet owner needs to recognize these changes promptly and respond appropriately. This isn’t always an easy task, particularly for new pet owners. So, to help you, here are ways to identify drastic changes in your pet’s behavior:

1. Loss of Appetite

  • Pets usually have specific feeding habits.
  • A sudden decline in food intake or an outright refusal of food that had previously been enjoyed can be a sign of some health or emotional issue.
  • Monitor their feeding pattern closely and try to identify any abnormal behavior.

2. Increased Aggression

  • An increase in aggression or sudden aggressive behavior can indicate a drastic change.
  • This might include snapping, growling, hissing, or even attempting to bite.
  • It could mean your pet is in pain or afraid.
  • If this behavior is inconsistent with your pet’s normal behavior, seek professional help immediately.

3. Lethargy

  • A significant decrease in your pet’s activity level might imply something wrong.
  • If your pet seems significantly less interested in activities it once enjoyed or seems excessively tired, these might be signs of a serious health issue.
  • Look for other signs of illness, like changes in eating or drinking habits, to corroborate your suspicion.

4. Excessive Vocalization

  • A drastic increase in your pet’s vocalization may also indicate a behavior change.
  • For dogs, this could mean more whining, barking, or howling.
  • This may mean more meowing or making noises more frequently than usual for cats.
  • This could signal stress, worry, or physical discomfort and should be adequately addressed.

What Factors Could Be Causing Behavioral Changes in Your Pet?

Various factors can influence your pet’s behavior. These include:

  1. Physical Health: Illness can change your pet’s behavior. A previously active dog might become quiet and withdrawn, or a usually independent cat can become overly attached.
  2. Environmental Changes: Environmental changes can also lead to altered behavior. A new family member, a move, or even a changed daily routine can upset pets. In such cases, services like emergency veterinary surgery can be integral to your pet’s health. In extreme cases, your pet might require urgent help from a veterinary surgeon specializing in addressing critical health issues in animals.
  3. Emotional Factors: Pets are emotional creatures, and their mood can affect their behavior. Separation anxiety, among other factors, can lead to behavior changes.
  4. Age and Lifecycle: As pets age, they go through physical and mental changes. This can result in behavior alterations due to discomfort or a decreased ability to handle stress.

Documenting Behavioral Changes

Maintaining a pet behavior journal can help track any changes in behavior. Document the following:

  • Types of Behavioral Changes
  • The Time the Behavior Occurred
  • The Frequency of the Behavior

Any patterns noted Sometimes, significant behavioral changes can mean the need for a detailed investigation, like in a veterinary lab in Westminster and Boulder. These labs have experienced staff to handle facilities for complex diagnostics and treatments.

Consulting with a Professional

A veterinarian should be consulted if behavior changes result in potential harm to the pet or people around it. They’ll perform:

  1. A Physical Examination
  2. Behavioral tests
  3. Evaluate case history

Veterinary Diagnostic Laboratory

An experienced veterinary diagnostic laboratory in Boulder can be an important resource for identifying drastic changes in a pet’s behavior. Veterinary diagnostic laboratories are specialized facilities that aid in diagnosing various medical conditions in animals that can alter behaviors. They use state-of-the-art machines to perform tests on samples collected from animals to diagnose various diseases and conditions. The role of these labs is generally two-fold:

Disease Diagnostics

Sometimes, changes in pet behavior could be due to hidden health issues. These issues are often identified through various tests, from blood tests to x-rays and biopsies. Veterinary diagnostic labs provide in-depth analysis results that can detect conditions causing behavioral changes in your pet.

Boosting Preventive Care

Such labs also help in supporting preventive care. Regular screening can discover health risks that might lead to behavioral changes in the long run before they escalate. This preventive strategy is especially valuable when managing conditions commonly known to lead to behavioral changes, like thyroid-related issues or joint pains.

Managing and Improving Changed Pet Behavior

Addressing a changed pet’s behavior requires multiple approaches. Here are some steps to consider:

  • Create a safe and engaging environment for your pet
  • Incorporate regular exercise and mental stimulation
  • Adjust diet based on pet’s requirements.

Remember, some critical situations can lead to emergencies. Facilities providing 24-hour emergency animal hospital services become instrumental in such cases. They are equipped to respond to critical situations promptly and efficiently. You can get the details here by visiting their website.

Implementing Changes and Observing Results

Changes should be implemented gradually. Patience is an essential virtue in this process. Keep tracking progress to observe how your pet responds to these changes.


Understanding and responding to pet behavior changes can be a challenging task. It’s crucial to approach it with love, patience, and understanding. As always, when things get tough, professional help should be sought. Your pet deserves a happy and healthy life, and you can help provide it with responsive and caring ownership.
