Grooming Practices
Brushing
Regular brushing:
- Distributes natural oils for shine
- Removes dead hair before it sheds on furniture
- Stimulates blood flow to skin
Additional tips: helps detect skin issues early, frequency depends on coat type (daily to weekly).
Choosing the Right Brush
- Slicker brush: Great for most coat types, removes mats
- Bristle brush: Good for short coats, distributes oils
- Undercoat rake: Essential for double-coated breeds
Additional tips: dematting comb: for tangles and mats, deshedding tools: help during shedding season.
Bathing
Proper bathing supports coat health:
- Use dog-specific shampoo (pH balanced)
- Don't over-bathe (strips natural oils)
- Every 4-6 weeks is typical, unless otherwise needed
Additional tips: rinse thoroughly—residue causes dullness and irritation, use conditioner for dry or long coats.
Managing Shedding
Some shedding is normal, but you can minimize it:
- Regular brushing removes loose hair
- Quality nutrition reduces excessive shedding
- Omega fatty acids help
Additional tips: regular bathing removes dead coat, de-shedding tools during seasonal changes.
When Shedding Is Abnormal
See your vet if you notice:
- Sudden increase in shedding
- Bald patches
- Excessive scratching with hair loss
Additional tips: skin changes accompanying hair loss, hair that doesn't regrow normally.
