When it comes to keeping your dog happy, you have to do more than just check for worms. Caring for and owning a dog can be a rewarding experience, but it also takes time and effort.

Doing the following core foundations of animal care will not only keep your pet healthy and happy but will allow you to identify other possible pet issues with greater ease. This is because the possibilities of other health-related issues will be minimized. Here are some essential tips on how to care for your  dog and maintain its health:

Vet Check-ups 

Schedule regular visits to the veterinarian for vaccinations, health screenings, and overall wellness examinations. Your vet can provide advice on nutrition, exercise, and any potential health concerns.

Proper Nutrition

You have to feed your dog a balanced diet with high-quality dog food appropriate for their age, size, and health condition. Always provide fresh water and avoid feeding them human food, especially items that can be toxic to dogs, like chocolate, onions, grapes, etc.

Exercise and Mental Stimulation

Dogs need regular exercise to stay healthy and prevent behavioral issues. Depending on the breed and age, dogs require different levels of physical activity. Daily walks, play sessions, and stimulating toys can benefit your dog.

Regular Grooming

Grooming keeps your dog’s coat clean and healthy. Brush their fur, trim their nails, clean their ears, and brush their teeth regularly. Grooming also allows you to check for any signs of skin issues, ticks, or fleas.

Training and Socialization

Proper training and socialization are important for a well-behaved and happy dog. Teach them basic commands and use positive reinforcement methods. Socialize your dog with other animals and people to help them become more confident and friendly.

Safe Environment

Ensure your home and yard are safe for your dog. Remove hazardous objects or substances that could harm them. You also have to provide a comfortable and quiet place for them to rest.

Identification and Microchipping

Make sure your dog always wears a collar with an ID tag that has your current contact information. Consider microchipping your dog as an additional safety measure to help identify them if they get lost.

Love and Attention

Dogs thrive on companionship and love. Spend quality time with your dog, show them affection, and make them feel like a valued member of your family.

Observe Behavior

Pay attention to changes in your dog’s behavior, eating habits, and bathroom routines. Sudden changes might indicate an underlying health issue that needs attention.

Caring for your pet in these ways will not only provide your dog with a great life, but will allow your veterinarian to focus on more significant health issues such as worms or parasites.

Worms and Parasites

Dogs can be affected by various types of worms and parasites. These parasites can lead to health issues if left untreated. 

Here are some of the most common dog parasites to keep an eye out for:


Roundworms are one of the most widespread intestinal parasites in dogs. Puppies can acquire them from their mother or through contaminated environments. Adult dogs can also get infected through ingestion of infected prey or contaminated soil.


Hookworms mostly infect the small intestines. They can cause anemia and other gastrointestinal issues in dogs. Infections can occur through ingestion, skin contact, or trans-mammary (mother-to-child) transmission in puppies.


Whipworms reside in the cecum (where the small and large intestines meet) and colon of dogs and can cause chronic diarrhea and other gastrointestinal problems. Dogs become infected by ingesting whipworm eggs from contaminated soil or feces.


Tapeworms are flat, segmented worms that attach to the intestinal lining of dogs. They are often acquired through the ingestion of infected fleas, rodents, or raw meat.


Heartworms are transmitted through the bite of infected mosquitoes. They primarily affect the heart and lungs and can cause lasting damage.  

Their effect can last past the time that the parasites are gone. Prevention and early treatment are important factors in managing this parasite.


Giardia is a parasite that can cause diarrhea and gastrointestinal upset in dogs. They are contracted through the ingestion of contaminated water or food.


Coccidia are single-celled parasites that can also cause diarrhea, weight loss, dehydration, and lethargy in dogs and puppies. They are typically transmitted through the ingestion of infected feces or contaminated environments.


Fleas are external parasites that feed on a dog’s blood. They cause itching and irritation and potentially transmit tapeworms.


Ticks are external parasites that can transmit various diseases to dogs. Lyme disease and Ehrlichiosis are common diseases spread by ticks.

How Do I Know My Dog Has Parasites

Detecting parasites in your dog can be challenging, as some infestations might not show any obvious symptoms. If you notice any of the following symptoms, it’s essential to consult your veterinarian for a proper diagnosis and treatment:

  • Visible worms
  • Change in appetite
  • Unexplained weight loss
  • Poor coat condition
  • Pot-bellied appearance
  • Vomiting or diarrhea
  • Lethargy
  • Visible anemia
  • Itching or scooting
  • Coughing
  • Change in behavior, such as restlessness or increased irritability

Prevent Parasites in Dogs

Preventing worms and parasites in dogs requires a combination of regular veterinary care, proper hygiene, and preventive measures. Here are some essential steps you can take to minimize the risk of your dog contracting worms and parasites:

Regular Veterinary Check-Ups

Schedule routine visits to the veterinarian for health checks and parasite screenings. Your vet can help detect and treat any potential issues early on.


Follow your veterinarian’s recommendations for regular deworming treatments. Puppies should be dewormed starting at two weeks of age and then at regular intervals until they are adults. Adult dogs should be dewormed at least once a year or more frequently if they are at higher risk.


Keep your dog up-to-date on all necessary vaccinations. Proper immunization helps strengthen your dog’s immune system, making it more resistant to infections.

Clean Living Environment

Regularly clean and disinfect your dog’s living area, including bedding, toys, and any other frequently used items. This reduces the chances of parasite eggs or larvae from developing and infecting your dog.

Proper Waste Disposal

Pick up and dispose of your dog’s feces promptly, especially in public areas. This helps prevent the spread of parasites to other dogs and reduces the risk of re-infection.

You should also prevent your dog from ingesting feces or coming into contact with soil that may be contaminated with parasite eggs or larvae.

Avoid Infected Animals

Limit your dog’s exposure to other animals that might be carrying worms or parasites. You need to be especially careful in areas known for a high prevalence of certain parasites.

Flea and Tick Prevention

Use veterinarian-approved flea and tick preventives to protect your dog from these parasites, as they can also transmit other diseases and internal parasites. There are a few options available to test them out to see what works best for you both.

Proper Nutrition

When you provide your dog with a balanced and nutritious diet, you’re helping them to support their immune system, making them less susceptible to parasites. If you’re unsure what to feed your dog for optimal results, you should consult your veterinarian. They’ll be able to assess the specific needs of your dog to give you the best options.

Spot Common Dog Parasites

When it comes to dog worms and parasites, prevention is key, and early detection is crucial. If you suspect your dog has worms or parasites or notice any unusual symptoms, contact your veterinarian immediately for proper diagnosis and treatment. Additionally, always follow your veterinarian’s advice and recommendations for your dog’s specific health needs.
