Additionally, Wednesday and Thursday are expected to be hot and humid — it is July in Maryland, after all — with highs in the 90s. That type of heat can can also be dangerous to pets. So make sure your pet has a means of cooling off. When walking, stay off of hot surfaces like asphalt because it can burn a dog's paws and keep the walks short. Make sure the pets have unlimited access to water, shade when they are outside and never leave a pet in a car, which can quickly overheat to deadly temperatures. Seek emergency veterinary care if any of these signs of heat stress are observed: anxiousness, excessive panting, restlessness, excessive drooling, unsteadiness, abnormal gum and tongue color, collapse.
