Vizsla Breeding Guide: Litter Size, Whelping, Puppy Weights and Health Testing
Updated September 6, 2026 · 6 min read · By the BreedBloom team
The Vizsla is a versatile sporting breed with a relatively sound health profile, where temperament, drive and working aptitude matter as much as clearances. Sebaceous adenitis and epilepsy are the breed's watch-list conditions.
Vizsla at a glance
Typical litter size
6–8 puppies (average around 7)
Birth weight
12–16 oz (340–450 g)
Adult weight
45–65 lb (20–29 kg)
Gestation
About 63 days from ovulation (57–72 from breeding)
Whelping
Usually free-whelping and attentive mothers. Short coat needs no clipping.
Breeding and whelping notes
Epilepsy has no DNA test; pedigree research and honest disclosure are the tools.
Sebaceous adenitis is present in the breed; skin biopsy screening in some programs.
Vizslas thrive on work and touch; puppies benefit from early exposure to water, birds and cover if going to hunting homes.
Thin coat: avoid cold whelping rooms and provide soft bedding.
Health testing before breeding
•
Hips: OFA or PennHIP
•
Eyes: annual CAER exam
•
Thyroid panel
•
Cardiac exam
•
Elbows: OFA

Keep the paperwork attached
Test results are only useful when they travel with the dog. Keep certificate numbers and dates on each dog's record and include copies in every go-home packet.
Tracking a Vizsla litter
Enter the ovulation or tie date and BreedBloom builds the Vizsla litter timeline: ultrasound window, X-ray count reminder, temperature checks, the day 3–16 ENS/ESI schedule, deworming and vaccination tasks, and per-puppy weight curves you can compare against the whole litter. Families follow along in the BloomPetz portal, and the go-home packet is assembled from the same records.
About these figures
