CBD Dosing Guidelines by Weight

Use this quick reference chart based on 1.45mg/kg base dosing rate. Adjust based on severity of symptoms.

Pet Weight	Weight (kg)	Mild (0.5x)	Standard (1x)	Moderate (1.5x)	Severe (2x)
10 lbs	4.5 kg	3 mg/day	7 mg/day	10 mg/day	13 mg/day
20 lbs	9.1 kg	7 mg/day	13 mg/day	20 mg/day	26 mg/day
30 lbs	13.6 kg	10 mg/day	20 mg/day	30 mg/day	39 mg/day
50 lbs	22.7 kg	16 mg/day	33 mg/day	49 mg/day	66 mg/day
75 lbs	34.0 kg	25 mg/day	49 mg/day	74 mg/day	99 mg/day
100 lbs	45.4 kg	33 mg/day	66 mg/day	99 mg/day	132 mg/day
150 lbs	68.0 kg	49 mg/day	99 mg/day	148 mg/day	197 mg/day

Example: A 50lb dog (22.7kg) at severe = 22.7kg × 1.45mg/kg × 2 = 66mg per day

💡 Always start with 50% of the recommended dose for the first 3-5 days, then increase to full dose if well-tolerated.

How Long Does CBD Take to Work in Dogs & Cats?

The onset time and duration of CBD effects depend on the product format and your pet's individual metabolism:

⏱️ Onset Times by Product Type

• CBD Tinctures (Relief+): 15-45 minutes for initial effects. Sublingual absorption (under the tongue) works fastest.
• CBD Treats (Bosco's Recipe): 30-60 minutes. Must be digested first, so effects take longer but last longer (6-8 hours).
• CBD Topicals (Derminol, Delta RX): 10-20 minutes for localized relief. Works directly on skin and doesn't enter bloodstream.
• CBD Supplements (Vigor): 45-90 minutes. Best results seen after 2-4 weeks of consistent daily use.

📅 Full Therapeutic Benefits Timeline

Week 1: You may notice initial calming effects or reduced anxiety within the first few doses.

Week 2-3: More consistent improvements in mobility, inflammation, and overall comfort as CBD builds up in the system.

Week 4+: Full therapeutic benefits for chronic conditions like arthritis, seizures, and inflammatory bowel disease. This is when the endocannabinoid system reaches optimal balance.

💡 Pro Tip: Give CBD at the same time each day for best results. Consistency is key for managing chronic conditions.

Frequently Asked Questions About CBD Dosing

What is the dosing rate used in this calculator?

This calculator uses a base rate of 1.45mg per kilogram, adjusted by severity multipliers (0.5x for mild, 1x for standard, 1.5x for moderate, 2x for severe). This provides a safe, effective range for most pets while allowing customization based on individual needs.

Can I give my dog too much CBD?

CBD has a very high safety margin. While it's difficult to overdose, giving too much can cause mild side effects like drowsiness, dry mouth, or temporary digestive upset. If this occurs, simply reduce the dose. Our dosing recommendations are well within safe limits.

Should I give CBD with food or on an empty stomach?

With food is best. CBD is fat-soluble, so giving it with a meal (especially one containing healthy fats) increases absorption by up to 5x. For fastest results, you can give tinctures on an empty stomach, but absorption will be lower.

How often should I give CBD to my pet?

For best results, split the daily dose into 2 servings (morning and evening). This maintains consistent CBD levels throughout the day. For acute situations like thunderstorms or vet visits, you can give a single dose 30-45 minutes before the stressful event.

Can I give my dog human CBD oil?

While human CBD oil isn't toxic to pets, it's not ideal. Pet-specific CBD is formulated for their smaller size and different metabolism. Human products may contain xylitol (toxic to dogs) or THC levels unsafe for pets. Always use pet-formulated CBD like VetsGrade's solventless products.

How much CBD for a 50lb dog with anxiety?

For a 50lb dog (22.7kg) with moderate anxiety, the recommended dose is 49mg CBD per day (1.5x base rate). For severe anxiety, increase to 66mg/day (2x base rate). This equals approximately 1.5-2 full droppers of Relief+ Tincture daily, split into morning and evening doses.

What's the difference between CBD dosing for dogs vs. cats?

The base dosing rate applies to both dogs and cats. However, cats are more sensitive to CBD and should always start at the lower end of the range. For cats, we recommend starting with 50% of the calculated dose and increasing gradually over 7-10 days while monitoring for any side effects.

Can I give CBD to my puppy or kitten?

CBD is generally safe for puppies and kittens over 8 weeks old, but always consult your veterinarian first. Use 50% of the calculated dose and monitor closely. Avoid giving CBD to pregnant or nursing animals without veterinary guidance.

Should I adjust the dose for senior dogs?

Senior dogs often benefit from the standard or moderate dosing levels due to age-related issues like arthritis and inflammation. Start with the standard dose and increase to moderate (1.5x) if needed after one week. Senior dogs may also need more time (4-6 weeks) to show full benefits.
