12 Harmful Things You Do To Your Dog Without Realizing It | March 22, 2025

Your dog is probably a loyal companion, full of energy and curiosity. You probably want him to live a long and healthy life. However, some of your habits, even well-intentioned ones, can be harmful to him without you realizing it. Here is a list of common mistakes that we unintentionally make and advice on how to remedy them, in order to guarantee the well-being of your faithful four-legged friend.

Choosing the Wrong Collar
Choosing the right collar for your dog is a crucial decision. There are several types of collars, and it is important to select the one that best suits his personality and specific needs:

Classic collar: The most common model, adjustable according to the size of your dog. It is practical and suitable for most dogs.
Anti-escape collar: This type of collar automatically detaches if there is a risk of strangulation (for example, if your dog gets stuck in a branch). Ideal for adventurous dogs.
Training collar: Designed for dogs in training, this type of collar is not necessary for puppies or young dogs.
Harness: If your dog pulls a lot on the leash, a harness can be a gentler option, as it distributes the pressure on his body and protects his throat.
Whatever you choose, always make sure to choose the right size. If the collar or harness is too big, your dog could escape; if it is too tight, it could lead to strangulation. The general rule is to be able to fit one finger between the collar and your dog’s neck for small and medium breeds, and two fingers for larger dogs. Remember to adjust the size of the collar regularly, especially if your dog is growing or has gained weight.

Leaving a dog alone in a car
Leaving your dog alone in a car, even for a few minutes, can be extremely dangerous. According to studies, the temperature inside a vehicle can increase by 6°C every ten minutes, even if the car is parked in the shade. If the temperature outside is 15°C, it can reach 43°C in the car in a short time. Unlike humans, dogs do not sweat to cool down. Heatstroke can therefore occur very quickly. Warning signs include excessive salivation, sudden fatigue, abnormal agitation, or vomiting and diarrhea. If you notice these symptoms, consult a veterinarian immediately.

Neglecting Dental Care
Your dog’s teeth need just as much attention as your own. Dental care isn’t just about aesthetics: poor oral hygiene can lead to serious health problems. It’s a good idea to start brushing your dog’s teeth from a young age. Three times a week may be enough to start with, but ideally, daily brushing is best. Use a brush and toothpaste that are specifically designed for dogs. There are some toothpastes with unusual flavors like chicken or beef that your dog will likely enjoy. Also, a visit to the vet twice a year for a professional cleaning is recommended.
