The growing popularity of CBD products isn’t limited to human consumption. Many pet owners are also exploring the use of CBD for their four-legged family members. From relieving chronic pain and inflammation to reducing anxiety and behavioral issues, CBD offers a range of benefits for dogs as well. If you have a large breed dog that weighs around 140 pounds and you’re wondering how much CBD to administer, this guide is for you.

The Benefits of CBD for Dogs

CBD, short for cannabidiol, is one of the non-psychoactive compounds found in the cannabis plant. Unlike THC, which is also found in cannabis, CBD doesn’t cause a high. For dogs, CBD can offer relief from a variety of symptoms including:

  • Anxiety and stress
  • Chronic pain
  • Inflammation
  • Seizures

The Optimal CBD Dosage For A 140 lb. Dog

The general guideline for a dog weighing around 140 pounds is to administer 28 mg of CBD.

Note: Start with a smaller dosage initially and monitor your pet’s response. If you don’t notice any changes, consider incrementing the dosage by 20-30%.

Types of CBD Products for Dogs

There are various forms of CBD products available for dogs:

  • CBD Oils: Oils are versatile and allow you to adjust the dose precisely. They can be given directly or added to food.
  • CBD Treats: These are easy to administer but offer less flexibility in dosage.
  • CBD Capsules: Capsules can be hidden in treats or the contents can be mixed with food.
  • CBD Topicals: These are applied directly to the skin and are best for localized issues.

Factors Influencing CBD Dosage

Several factors can affect how much CBD your dog may need:

  • Age: Older dogs may have different metabolic rates than younger ones.
  • Health Conditions: Chronic issues may require a different dose than temporary or less severe conditions.
  • Other Medications: Interactions can occur between CBD and other drugs.

How to Administer CBD

The mode of administration can affect the bioavailability of CBD:

  • Direct Oral Administration: Offers quick absorption but can be tricky if your dog dislikes the taste.
  • Mixed with Food: Easier to administer, but might take longer to be effective.
  • Topical Creams: Best for localized conditions like skin issues or joint pain.

Monitoring and Adjusting Dosage

It’s essential to carefully observe your dog after administering CBD:

  1. Immediate Reaction: Look for any signs of immediate discomfort or allergic reactions.
  2. Long-term Monitoring: Keep an eye out for any improvements or the lack thereof in the condition you are trying to treat.

If you don’t observe any significant changes, consider increasing the dosage by 20-30%. Always consult your vet before making any changes.

Importance of Veterinary Guidance

Though CBD is generally considered safe for dogs, it should not replace veterinary advice. A vet can provide a comprehensive health plan and offer guidance on how CBD can fit into that plan, especially when other medications are involved.

Potential Side Effects

While CBD is generally well-tolerated, some dogs might experience:

  • Dry mouth
  • Slight drowsiness
  • Minor changes in appetite or weight

Consult your vet if you observe any of these symptoms in your pet.
