- Size: medium (30-40 lbs)
- Energy Level: High
- Shedding: Moderate

- Lifespan: 12-14 yrs
Weight Chart by Age
Care that accounts for breed predispositions leads to earlier detection and better prevention. Practical Brittanys care is shaped by three things: medium size, moderate shedding, and a known predisposition to hip dysplasia and epilepsy.
Staying proactive with vet visits — based on your pet's age and breed risks — is the most affordable way to manage breed-specific conditions. Given the breed's health tendencies, proactive screening is important for this breed.
Male vs Female Size
The key to a happy, healthy Brittany is matching your care approach to their breed characteristics. High-energy breeds need physical and mental outlets every day — without them, behavioral problems like destructive chewing or excessive barking are common.
- Aim for 1-2 hours of activity daily, mixing walks with play and training to keep things engaging
- Feed a high-quality diet formulated for medium breed dogs (800–1,200 calories/day)
- Maintain a 2–3 times per week grooming routine
- Schedule breed-appropriate health screenings for hip dysplasia
- Pet insurance enrolled early typically offers the best value, covering breed-related conditions before they develop
Factors Affecting Size
The details that distinguish this breed from similar breeds matter for long-term health and wellbeing. As a sporting breed, the Brittany has instincts and behaviors shaped by centuries of selective breeding for specific tasks.
Many experienced Brittany owners recommend dog sports like agility, flyball, or nosework to channel their energy productively.
Enrichment does not require expensive equipment. For Brittany, simple activities like hiding treats around the house for discovery, using a muffin tin with tennis balls over kibble, or practicing basic obedience in new locations provide effective cognitive engagement. The goal is not complexity — it is variety and appropriate challenge level.
When They Stop Growing
Knowing what to watch for gives you a real head start on breed-related problems. Watch for early signs of hip dysplasia, maintain regular veterinary visits, and keep your dog at a healthy weight — excess weight worsens most of the conditions Brittanys are prone to.
A consistent daily schedule reduces stress hormones measurably — animals that know what to expect spend less energy on vigilance and more on rest and recovery. Set up regular times for meals, activity, grooming, and rest. High-energy Brittanys especially benefit from knowing when their exercise time is coming — it helps them settle during calmer periods.
Veterinary Care Schedule for Brittanys
Regular veterinary visits allow early detection of breed-associated conditions, when treatment is most effective. The recommended schedule for your Brittany. Below is a general framework.
| Life Stage | Visit Frequency | Key Screenings |
|---|---|---|
| Puppy (0-1 year) | Every 3-4 weeks until 16 weeks, then at 6 and 12 months | Vaccinations, deworming, spay/neuter (consult AVMA guidelines on optimal timing) consultation |
| Adult (1-7 years) | Annually | Physical exam, dental check, heartworm test, vaccination boosters |
| Senior (7+ years) | Every 6 months | Blood work, urinalysis, Hip Dysplasia screening, Epilepsy screening, Hypothyroidism screening |
Brittanys should receive breed-specific screening for hip dysplasia starting at 3-5 years of age or earlier if symptoms appear. Catching problems early gives you more treatment options and better odds.
