Prednisone for Dogs: Uses, Side Effects, and Safety
Prednisone is a corticosteroid that reduces inflammation and immune system activity. It's commonly prescribed for allergies, autoimmune diseases, arthritis, and certain cancers in dogs.
If your dog has been prescribed prednisone, you're not alone. Prednisone is one of the most commonly used medications in veterinary medicine. This guide explains what prednisone is, why it's prescribed, common side effects, and what to expect when your dog is taking it.
What Is Prednisone?
Prednisone is a corticosteroid medication. It works by reducing inflammation and calming down an overactive immune system. In veterinary medicine, it's used "off-label," meaning it's not specifically FDA-approved for dogs but is widely prescribed by veterinarians.
Common Uses of Prednisone in Dogs
- Allergies and skin problems - itching, rashes, hot spots
- Autoimmune diseases - immune-mediated thrombocytopenia or anemia
- Arthritis and joint pain - reducing inflammation in joints
- Certain cancers - shrinking tumors and improving comfort
- Neurological inflammation - spinal or brain inflammation
For dogs with severe allergies that haven't responded to other treatments, prednisone can provide significant relief when medications like Apoquel aren't suitable or effective.
Prednisone Side Effects in Dogs
Most common side effects (especially short-term use):
- Increased drinking and urination - most noticeable side effect
- Increased appetite - may lead to weight gain
- Panting or restlessness - especially at night
- Mild behavior changes - increased energy or anxiety
With long-term use, more serious side effects can develop, such as:
- • Thinning of the skin or coat changes
- • Muscle weakness
- • Increased risk of infections
- • Liver enzyme elevations
- • Cushing's-like symptoms (pot-bellied appearance, hair loss)

Try VetLens FreeDosage and Safety Considerations
The dose your vet prescribes depends on your dog's weight, condition, and how severe the problem is. Prednisone is often started at a higher dose and then tapered down over time. Never stop prednisone suddenly without veterinary guidance, as this can cause dangerous adrenal crises.
Important Safety Note:
Prednisone should be used with caution in dogs with diabetes, kidney or liver disease, or active infections.
Monitoring Your Dog on Prednisone
- • Your veterinarian may recommend regular bloodwork to monitor liver enzymes, electrolytes, and immune function during long-term treatment
- • You can also keep track of your dog's symptoms, appetite, weight, and behavior at home
- • Understanding CBC results can be helpful if your vet orders bloodwork while your dog is on prednisone
- • For dogs with low platelets, prednisone is often a first-line treatment
When to Call Your Vet
Contact your vet if your dog develops vomiting, diarrhea, sudden lethargy, signs of infection, or if side effects seem severe. Always check before giving prednisone alongside other medications, especially NSAIDs like Rimadyl, since this can increase the risk of stomach ulcers.

Frequently Asked Questions
How long can a dog stay on prednisone?
Some dogs only need prednisone for a short course (a few days to weeks). Others may stay on it long-term for chronic conditions. In long-term cases, vets use the lowest effective dose.
Can prednisone be used with other medications?
Yes, but it must be carefully managed. Certain drugs (NSAIDs, some antibiotics) can cause harmful interactions. Always tell your vet everything your dog is taking.
What happens if I miss a dose?
If it's only been a short time, give the dose as soon as you remember. If it's close to the next scheduled dose, skip it and resume the normal schedule. Do not double up.
Can prednisone cure my dog's condition?
Prednisone doesn't cure most underlying diseases, but it can dramatically reduce inflammation, relieve symptoms, and improve quality of life.
