Spring in Michigan brings longer days, rising temperatures, melting snow, and more time outdoors with your pets. It also introduces several spring pet health problems that dogs and cats commonly face in the Midwest. Understanding these seasonal risks can help you keep your pet healthy and comfortable with guidance from Schoolcraft Veterinary Clinic.
1. Flea, Tick, and Mosquito Risks Begin Early in Spring
As temperatures rise above freezing, fleas and ticks become active again in Michigan. They survive winter in protected areas such as leaf litter, brush piles, and under decks. When spring arrives, pets can pick them up while exploring thawing yards, damp ground, wooded trails, and areas with wildlife activity.
These parasites may cause skin irritation, infections, and tick-borne diseases such as Lyme disease and Anaplasmosis. Both illnesses are transmitted through the bite of an infected tick, which makes early spring tick prevention especially important.
Mosquitoes also begin emerging as Michigan warms, and they spread heartworm disease. Even one bite can put your pet at risk. Because even indoor pets can be bitten by mosquitoes, heartworm prevention is essential throughout spring and summer.
Consistent, year-round prevention is one of the most important steps for protecting your pet from fleas, ticks, and heartworm as Michigan enters spring.
2. Shedding and Seasonal Coat Changes
After a long Michigan winter, many pets begin shedding their thick cold-weather coats. Dogs with double coats may shed heavily, while cats often develop more hairballs or small mats. Regular brushing helps reduce loose hair and makes it easier to notice any developing skin issues.
Some pet owners ask how to stop dog shedding as spring arrives. While shedding is natural and cannot be stopped completely, it can be managed through good coat care:
- Brush regularly to remove loose hair before it spreads around the home.
- Feed a balanced diet that supports healthy skin.
- Most dogs do well with a bath every 4–6 weeks to help loosen dead hair without drying out the skin. If your dog has a skin condition or special grooming needs, the veterinarians may recommend a schedule tailored to them.
- Use parasite prevention consistently, as itchy flea bites often cause additional shedding.
- Watch for bald patches, dandruff, or irritated skin that may signal a developing concern.
If your pet sheds more than usual or develops skin changes, scheduling an exam can help determine whether something else is contributing to the change.
3. Spring Hazards That Can Lead to Digestive Issues or Illness
As snow melts, pets gain access to materials that were hidden all winter. In Schoolcraft, common spring causes of digestive upset include moldy leaves, early mushrooms, acorns or seed pods, compost, wildlife droppings, fertilizer residue, and areas of stagnant or standing water.
These exposures can cause vomiting, diarrhea, or sudden illness. If your pet eats something potentially toxic — such as mushrooms, compost, or a harmful plant — contact the clinic right away. If you are not sure what they ate or symptoms appear, it is safest to call rather than wait.
Spring rains and melting snow also create puddles, muddy patches, and areas of slow-draining water where bacteria thrive. One concern in Michigan is Leptospirosis, a disease spread through urine from infected wildlife. Dogs can be exposed simply by walking through or drinking from contaminated standing water.

4. Toxic Plants and Yard Products

As Michigan lawns wake up for spring, many plants and products become active hazards. Local concerns include tulips, daffodils, hyacinths, crocuses, lily of the valley, and any bulbs dug up by curious pets. Lilies are especially dangerous and are life threatening for cats.
Yard products also require care. Fertilizers, herbicides, pesticides, and weed preventers can be harmful if pets walk through treated areas or lick product from their paws. Store all chemicals securely, follow label instructions closely, and allow sprayed areas to dry before letting pets outside.
5. Wildlife Encounters After the Thaw
As animals become more active in spring, dogs and cats may encounter raccoons, skunks, squirrels, and other wildlife. These interactions can lead to bites, scratches, or parasite exposure. Keeping pets supervised outdoors and avoiding brushy, wooded, or wet areas helps reduce these risks.
