Tick and flea season for dogs arrives earlier—and lasts longer—than many pet owners expect. In many areas, tick activity begins weeks before spring officially arrives, especially during mild winters. For dogs, that means more itching, irritation, and health risks if pests go unnoticed. From a groomer’s perspective, early detection and routine checks make a real difference.
This guide explains when tick and flea season for dogs starts, what dog owners can do at home, and when it’s time to call a professional groomer.
When Does Tick and Flea Season for Dogs Start?
Tick and flea activity is driven by temperature, not the calendar.
- Ticks become active when temperatures rise above ~40°F
- Fleas thrive in warmer, humid conditions (65°F and up)
In many parts of the U.S., this means:
- Early spring (March–April) is the real beginning
- Peak season runs May through September
- Fall activity can continue into October or November
- In warmer regions, there may be no true off-season
This is why veterinarians and groomers often see tick issues before pet owners think the season has started.
Why Groomers Spot Ticks and Fleas First
Professional groomers are trained to examine areas that are easy to miss at home. During a grooming appointment, we routinely check:
- Behind and under the ears
- Around the collar and neck
- Armpits and inner legs
- Groin and tail base
- Between paw pads and toes
Dense coats, double coats, and longer hair can hide pests for weeks. Many owners only discover a problem once itching, redness, or skin irritation appears.
What Dog Owners Can Check at Home
Regular at-home checks help catch problems early—especially between grooming appointments. During peak tick and flea season for dogs, routine coat checks become especially important for early detection.
1. Do a Quick Daily Scan
After walks, hikes, or yard time:
- Run your hands slowly over your dog’s body
- Feel for small bumps, scabs, or raised areas
- Pay attention to areas where the fur is thick or matted
Ticks are often easier to feel than see.
2. Inspect Ears and Neck Weekly
Use your fingers to gently part the hair:
- Around the ears and ear base
- Under the collar
- Along the neckline
Ticks love warm, protected areas.
3. Check Paws and Legs
Ticks commonly latch onto:
- Paw pads
- Between toes
- Lower legs after walks in tall grass
Lift each paw and look carefully.
4. Watch for Behavioral Signs
Call a groomer or vet if you notice:
- Excessive scratching or chewing
- Head shaking
- Red or irritated skin
- Sudden sensitivity when touched
These can be early signs of fleas or tick bites. According to the CDC, ticks can become active when temperatures rise above 40°F, even before spring officially begins.
When It’s Time to Call a Groomer
A professional groomer should be involved when:
- Your dog has a thick, long, or double coat
- Mats or tangles make home checks difficult
- You’ve found one tick and suspect more
- Your dog resists handling during checks
- It’s been several weeks since the last professional groom
Mobile groomers are especially helpful during tick and flea season because they:
- Provide one-on-one attention
- Reduce exposure to other pets
- Can spot skin issues early in a calm environment
Many groomers can safely remove ticks and recommend next steps if irritation or infection is present.
Prevention Starts With Routine Grooming
While flea and tick preventatives are essential, regular grooming is part of prevention, not just appearance.
Routine grooming helps:
- Detect ticks before they embed
- Remove loose hair where fleas hide
- Keep skin healthy and visible
- Reduce matting that traps pests
Dogs on a consistent grooming schedule tend to have fewer severe infestations because problems are caught early.
Final Thoughts
Tick and flea season doesn’t wait for summer—and neither should prevention. Regular at-home checks combined with professional grooming give dogs the best protection during peak pest months.
If you’re unsure whether your dog needs a professional grooming check, it’s always better to schedule early than wait for symptoms to appear.
