"Dog allergy shot" can mean three different things: a Cytopoint injection, an Apoquel prescription, or allergen immunotherapy. This article explains each cost and when each is the right choice.
Three Categories of "Allergy Shot"
| Shot type | Mechanism | How it's administered | Cost range |
|---|---|---|---|
| Cytopoint (lokivetmab) | Monoclonal antibody blocking IL-31 (the itch cytokine) | Vet-administered subcutaneous injection every 4–8 weeks | $50–$400/injection |
| Apoquel (oclacitinib) | JAK inhibitor that suppresses itch signalling pathways | Daily oral tablet (not an injection, but often called an "allergy pill") | $45–$92/month |
| Allergen immunotherapy ("ASIT") | Custom serum with tiny amounts of identified allergens, training the immune system to tolerate them | Subcutaneous (allergy shots) every 1–2 weeks, or sublingual drops daily | Initial $800–$1,200; maintenance $300–$700/year |
| Steroid injections (long-acting) | Cortisone depot that suppresses immune response broadly | Vet-administered, lasting 4–8 weeks (deprecated for chronic use due to side effects) | $40–$120/injection |

Cytopoint Allergy Shot Cost
From the Cluster D pillar:
| Weight tier | Per shot | Annual (6-week schedule) |
|---|---|---|
| Small (<20 lb) | $50–$140 | $585–$1,170 |
| Medium (30–50 lb) | $130–$250 | $1,170–$2,250 |
| Large (60–80 lb) | $170–$320 | $1,530–$2,880 |
| Giant (110+ lb) | $320–$560 | $2,880–$5,040 |

Why Cytopoint is the most common "first-line" allergy shot:
- Single injection lasts weeks
- Highly targeted mechanism (less systemic immunosuppression)
- Approved for dogs over 12 months of age
- Safe combination with most other allergy meds
Apoquel Cost
Although Apoquel is technically an oral tablet, it is often compared to Cytopoint as the alternative "allergy medication":
| Size of dog | Daily Apoquel dose | Monthly cost |
|---|---|---|
| Under 14 lb | ½ tablet of 3.6 mg or 5.4 mg | $45–$55 |
| 15–29 lb | ½ tablet of 16 mg | $50–$70 |
| 30–59 lb | 1 tablet of 16 mg | $75–$100 |
| 60–89 lb | 1.5 tablets of 16 mg | $90–$110 |
| 90+ lb | 2+ tablets of 16 mg | $92–$120 |
Annual cost: $540–$1,440 (essentially the same regardless of dog size)

Apoquel generic (oclacitinib) launched in 2025; in 2026 ask your vet about the generic, which is roughly 40–60 % cheaper than the brand.
Allergen Immunotherapy Allergy Shot Cost
The closest thing to a "permanently effective allergy shot." A combination of allergy testing and immunotherapy:
| Component | Cost (2026) |
|---|---|
| Intradermal skin test (gold standard) | $250–$600 |
| Serum IgE test | $200–$500 |
| Compounded immunotherapy serum (custom per dog) | $300–$500 induction; $50–$80/month maintenance |
| Veterinary dermatologist consult | $150–$300 |
| Rush immunotherapy (alternative) | One-time $1,200–$2,000 with quicker ramp-up |
| Owner/administered injection kit | Often supplied; no office fee |

Time to efficacy: 6–12 months for noticeable improvement; 12–24 months for maximum effect.
Success rates: ~70–80 % of dogs show measurable improvement; ~50 % of dogs reduce or eliminate other allergy medications.

Steroid Injection Cost
Long-acting steroid injections (such as methylprednisolone acetate) are now considered second- or third-line due to side effects but are still used in acute flare-ups:
| Steroid injection | Cost per injection | Duration | Side effects |
|---|---|---|---|
| Methylprednisolone acetate (Depo-Medrol) | $50–$120 | 4–8 weeks | Increased thirst, increased appetite, muscle wasting, possible Cushingoid features with chronic use |
| Triamcinolone acetonide | $40–$100 | 4–8 weeks | Similar |
Sources: Vetster — Steroid use in dogs; WebMD — Steroid side effects in dogs.
Most dermatologists now recommend steroid injections be limited to 1–2 doses per year maximum, often as a bridge while waiting for Cytopoint or Apoquel to start working.

| Young dog (under 12 months) | Cytopoint (only approved option) |
| Multi-modal allergy + skin infection | Cytopoint + Apoquel + antibiotic |
| Identifiable allergens; want to reduce lifetime meds | Allergen immunotherapy after testing |
| Seasonal allergies only | Cytopoint for season + immunotherapy long-term |
| Severe year-round allergies | Combination therapy + immunotherapy |

Three-Year Cost: All Three Compared
A 30-lb dog with year-round environmental allergies, three-year total:
| Option | 3-year cost | Comments |
|---|---|---|
| Cytopoint only | $3,390 to $4,110 | $1,130–$1,370/yr × 3 years |
| Apoquel only | $3,300 to $3,600 | $1,100–$1,200/yr × 3 years |
| Cytopoint + Apoquel bridge | $4,290 to $5,040 | $1,430–$1,680/yr × 3 years |
| Allergen immunotherapy + Cytopoint first year | $2,680 | Testing first + Cytopoint first year + immunotherapy maintenance in years 2–3 |
| Allergen immunotherapy only | $2,400 to $3,000 | Often insufficient alone, requires adjunct in first year |

Are Cytopoint and Apoquel the same thing? No. Cytopoint is a monoclonal antibody injection that blocks IL-31. Apoquel is a JAK inhibitor oral tablet.
Which is cheaper? Apoquel is cheaper for medium/large dogs. Cytopoint is cheaper for small dogs. For most dog sizes, Apoquel is more price-stable over time because the dose is fixed regardless of weight.
Do allergy shots cure allergies? No. Cytopoint and Apoquel suppress symptoms. Only allergen immunotherapy addresses underlying immune dysregulation.
Can allergy shots be given by owners at home? Cytopoint requires vet administration. Apoquel is an oral tablet at home. Allergen immunotherapy can be done at home by the owner, often with a vet training session first.
How long do allergy shots take to work? Cytopoint: 1–3 days. Apoquel: 4 hours. Steroid injection: 12–24 hours. Allergen immunotherapy: 6–12 months for noticeable benefit, 12–24 months for maximum effect.
