For relief of pain caused by arthritic conditions it’s best to use a medicine with stronger antiinflammatory effects such as Previcox.
Note: Because acetaminophen is not commonly used to treat animals information is limited about its safety. For this reason you should talk to your vet to discuss the best possible treatment options before giving Tylenol to your pet.
Before use you should check the medicine’s packaging to see if acetaminophen is the only active ingredient. Some products containing additional ingredients such as codeine can also be used to treat dogs but the dosing may be different. When using medicines containing acetaminophen as the only active ingredient (e.g. the plain Tylenol formula) a dose of 6.8 mg/lb (15 mg/kg) can be given every 8 hours.
Refer to the chart and calculator below to find the right dosage for your dog.
If you are using Tylenol No. 4 the dosage should be based on the codeine content. The recommended dosage is 0.5 – 0.9 mg/lb codeine every 6 to 8 hours. This means a dog weighing 60 lbs could be given half of one tablet (30 mg codeine and 150 mg acetaminophen) per dose.
Degenerative Myelopathy: A dose of 2.2 mg/lb may be given to German Shepherds once daily to treat degenerative myelopathy. Do not exceed 9 mg/lb on any day.
