Vetoquinol Zylkene Calming Capsules for Dogs & Cats, 30ct

Zylkene is a once-daily capsule that helps dogs and cats stay calm and settled during the situations that unsettle them most — travel, boarding, visitors, fireworks and thunderstorms, a move, or a change in routine. Its single active ingredient is alpha-casozepine, a peptide derived from hydrolyzed bovine milk protein.

Zylkene supports balanced behavior without sedation, so your pet stays alert, engaged and fully themselves. It is lactose-free, free of preservatives, and made by Vetoquinol — a veterinary-exclusive animal health company founded in 1933 and holding the NASC Quality Seal.

Capsules can be given whole or opened and sprinkled over food, which makes daily dosing simple even for cats and pill-averse dogs. Zylkene works best given daily over a stretch of time rather than as a single dose before an event, so start it ahead of a planned change and give it time to work.

Key Benefits:

• Supports calm, balanced behavior during travel, boarding, visitors, loud noises and changes in routine
• Non-sedating — helps pets stay calm without changing their personality
• Single, well-characterized active ingredient derived from milk protein
• Lactose-free and preservative-free
• Give whole or open and sprinkle over food
• Suitable for both dogs and cats

Choosing a Strength & Daily Dose:

• 75 mg — cats and dogs up to 10 lb: 1 capsule daily; 11–22 lb: 2 capsules daily
• 225 mg — dogs 23–32 lb: 1 capsule daily; dogs 33–65 lb: 2 capsules daily; cats over 22 lb: 1 capsule daily
• 450 mg — dogs 33–65 lb: 1 capsule daily; dogs 66–132 lb: 2 capsules daily

Note: dogs in the 33–65 lb range can be dosed with either two 225 mg capsules or one 450 mg capsule. The 450 mg is usually the simpler and more economical choice at that weight.

Directions for Use:

• Give once daily, whole or opened over food, or as directed by your veterinarian.
• Begin 1–2 days ahead of an anticipated event where possible; some pets do better started 5–7 days ahead.
• For ongoing situational stress, give daily over several weeks.
• Talk with your veterinarian before starting Zylkene if your pet is taking any medication.
