Weekly Dog Health and Climate News
This week’s most important pet-health developments center on environmental exposure, emerging parasites, and preventable infectious disease. Wildfire smoke drifting across large areas of North America is creating respiratory risks for dogs and cats, especially flat-faced breeds, seniors, and animals with heart or lung disease. Veterinarians are also warning about the return of the New World screwworm in parts of the Southwest, where even small wounds may become vulnerable to infestation. A confirmed rabies case in a bat reinforces the importance of vaccination and avoiding wildlife contact. For cat owners, new research also strengthens the case for supervised rather than free-roaming outdoor access.

Summary: Smoke from Canadian wildfires is again affecting communities across the Midwest and East Coast, prompting animal-welfare groups to urge owners to reduce their pets’ exposure. The report recommends keeping dogs indoors as much as possible when air quality deteriorates, particularly when the Air Quality Index rises above 100. Outdoor exercise should be shortened and made less strenuous, and fresh water should remain readily available. Warning signs of smoke exposure include coughing, wheezing, labored breathing, excessive panting, watery eyes, nasal discharge, unusual fatigue, and loss of appetite. Dogs with short muzzles, cardiovascular disease, respiratory conditions, or advanced age may be especially vulnerable because they have less respiratory reserve and may struggle sooner when smoke and heat occur together.
Why This Matters: Check the local AQI before walks and move exercise indoors when conditions are unhealthy. Contact a veterinarian promptly if your dog develops breathing difficulty, persistent coughing, unusual weakness, or reduced appetite during a smoke event.
Parasites

Category: Parasites
Summary: Veterinarians are urging pet owners in Texas and New Mexico to watch for New World screwworm after confirmed cases included infections in dogs. Unlike most fly larvae, screwworm larvae feed on living tissue. Female flies may lay eggs in open wounds, surgical sites, bites, or irritated skin, and the larvae can cause severe pain, tissue damage, infection, shock, and death if treatment is delayed. Owners are advised to inspect dogs regularly for cuts, tick bites, or moist wounds and to watch for visible larvae, an unpleasant odor, restlessness, or repeated chewing at one area. Veterinary treatment can be successful when started quickly. The article also notes that prescription flea and tick preventives may help kill larvae and reduce risk, but product choice should be discussed with a veterinarian.
Why This Matters: Dogs that spend time outdoors should be checked daily for wounds, especially in affected regions. Any moving larvae, foul-smelling wound, sudden pain, or obsessive licking requires immediate veterinary attention rather than home treatment.
Infectious Disease

Summary: Racine County public-health officials reported that a bat tested positive for rabies, renewing warnings about contact between pets and wildlife. Rabies is uncommon in people in the United States but remains almost invariably fatal once symptoms develop. Dogs may be exposed through bites or saliva from infected bats, skunks, raccoons, foxes, and other mammals. Officials emphasized keeping rabies vaccinations current, avoiding direct handling of wild animals, and contacting both a veterinarian and local health authorities when a pet has fought with or mouthed wildlife. Bat encounters deserve particular caution because bite marks can be difficult to see. Prompt action after a suspected exposure allows health professionals to determine whether booster vaccination, quarantine, observation, or other measures are needed.
Why This Matters: Confirm that your dog’s rabies vaccination is current and keep the certificate accessible. Never release or discard a bat involved in a possible exposure until animal-control or public-health officials advise what to do.
