Tip: mosquito season and heartworm, what my sister learned

My sister has a mixed dog in Bang Bo. She keeps him inside most of the time with the air con on, so she thought heartworm was only a problem in the countryside. Last year she skipped the monthly pill for about four months. Then he started coughing after walks and got tired very fast on the stairs. The vet did a blood test and it was positive. The treatment is long and expensive, and they had to keep him very still for weeks, which was hard for a dog who never sits still. He is okay now, but she says she would never skip it again. Mosquitoes still get into the house even with the door closed, especially after rain. Indoor dogs are not safe. Ask your vet for a test once a year, and keep the monthly medicine on the same day each month. Put it in your phone so you do not forget. Do not buy the cheap ones online without checking the dose for your dog's weight. Anyone with a dog in the rainy season, please do not wait.
