Top Picks Summary
Zylkene 225 mg Capsules for Dogs
Zylkene holds a best-in-class position for targeted separation and noise phobia support because it delivers a single, milk-derived peptide (alpha-casozepine) in a drug-free, easy-to-dose capsule that many owners find predictable for daily use. Compared with pheromone-based Adaptil and multi-ingredient chews, Zylkene’s simplicity reduces interactions with other medications and often provides a cost-effective option for long-term maintenance without the regulatory or quality-variability concerns sometimes seen with hemp/CBD products.

Adaptil Calm Tablets
Adaptil is the market leader for environmental calming thanks to decades of pheromone research and a broad product line that includes diffusers, collars and now oral formulations, giving households an economical way to manage home-based separation and noise triggers. Technically distinct from oral nutraceuticals like Zylkene or hemp chews, Adaptil’s pheromone approach complements those products—providing low-cost, continuous environmental coverage while owners use edible supplements for on-the-go or acute episodes.
VetriScience Composure Calming Chews for Dogs
VetriScience Composure Pro Chews earn a market-leader reputation among veterinary-formulated options by combining clinically oriented nutrients in a palatable chew designed for faster onset and consistent dosing during acute separation or storm events. Though typically at a premium price versus mass-market brands like NaturVet, Composure Pro’s veterinary backing and targeted nutrient profile offer technical advantages for dogs who need a more robust, evidence-informed approach than single-ingredient or hemp-based alternatives.

Solliquin Calming Behavioral Health Supplement for Cats
Solliquin is positioned as a best-in-class targeted anxiety supplement for separation and noise phobias because it uses a veterinary-formulated, plant-forward approach designed to support acute behavioral episodes and stress reactivity. Compared with Purina's Calming Care, Solliquin emphasizes a proprietary botanical and neuro-support blend that many clinicians prefer for focused, short-term relief, though it is typically sold through veterinary channels at a premium.
NaturVet Quiet Moments Calming Aid Soft Chews
NaturVet Quiet Moments is positioned as a budget-friendly, widely available calming aid that combines multiple calming nutrients to help dogs prone to separation anxiety and noise phobias, making it attractive for price-sensitive owners or multi-dog households. While it may not offer the single-ingredient specificity of Zylkene or the veterinary-grade formulation of VetriScience, its lower price point and retail ubiquity make it an accessible first-step option before investing in higher-cost or specialized therapies.
Purina Pro Plan FortiFlora Probiotic Chews
Purina Pro Plan Calming Care is the market leader for long-term, cost-conscious management of separation and noise anxiety, combining Purina's research-backed manufacturing and broad retail availability to make daily use practical for many pet owners. Versus Solliquin, Purina's product is generally more affordable and easier to source for ongoing maintenance, offering broad nutritional and calming support rather than the concentrated botanical focus of the veterinary-only alternative.
What the Research and Veterinary Guidance Say
Clinical and laboratory studies, along with veterinary practice experience, support specific ingredient classes for reducing anxiety-related behaviors in dogs. Evidence is strongest for certain nutraceuticals and pheromone-based therapies, while the data for newer options such as hemp-derived cannabinoids is still emerging. Veterinarians recommend using supplements as part of a broader behavior plan and monitoring response and side effects closely.
Alpha-casozepine (product example: Zylkene) is a milk protein derivative with multiple studies showing reductions in stress-related behaviors and physiological stress markers in dogs when used as directed.
L-theanine and related amino acids have evidence for promoting calmness without sedation; they are commonly included in chews and tablets to help with situational anxiety.
Dog appeasing pheromone (DAP) approaches, such as those used in Adaptil products, demonstrate benefit for some dogs in reducing fear and promoting calm in stressful situations when used alongside training.
Multi-ingredient formulas combining amino acids, vitamins, and plant extracts can help, but study quality and consistency vary; look for products with published trials or veterinary formulation.
Hemp-derived ingredients and CBD show promising preliminary results, but robust randomized controlled trials in dogs are limited and regulatory guidance in Canada is evolving. Discuss these options with a veterinarian.
High-quality evidence consistently supports the value of a multimodal strategy: combine supplements with behavior modification, environmental changes, and, when appropriate, veterinary-prescribed medications for best outcomes.
