Bones
Bones of any kind should not be given to dogs. A piece of bone can get lodged in the throat, sharp parts of the bone can do damage to the throat and other soft tissues in the digestive system, and they can get stuck in the windpipe.
Small Balls
Your dog should not be allowed to play with balls that are small enough to fit in his throat. In addition, a ball with an air hole in it can cause a suctioning hazard that will choke your pet. The only type of balls your dog should play with are ones that are made for them. There are balls made especially for dogs of all sizes at major pet stores or even at your veterinarian’s office.
Childrens’ Toys
Although toys are supposed to be safe for children, most of them are not safe for your dog. Especially if your dog likes to chew, which all dogs usually do. No matter how well the toy seems to be made, your dog can probably chew on it enough for it to be dangerous. There are toys made for dogs that you can give your dog that are much safer.
Sticks
Sticks can be a problem as well, especially if your dog is unattended outside for any amount of time. These things may seem innocent enough, but wood swells when it gets wet and can get lodged in the throat or intestines.
Swelling of the Throat
There are many things that can cause swelling of the throat such as injury, swallowing corrosive material, or allergies. If your dog has an allergic reaction and his breathing becomes labored, take him to the emergency animal hospital right away. This is a sign of anaphylactic shock and may cause your dog’s throat to swell shut, causing suffocation and death.
Collapsed Trachea
A tracheal collapse is not common in most dogs, but common in small brachycephalic dogs with short muzzles such as the Shih Tzu, Pomeranian, Lhasa Apso, Maltese, Poodle, Yorkshire Terrier, Pug, and Chihuahua. This is a serious condition that can be fatal if not treated right away.
If your dog has a collapsed trachea he will likely be wheezing, have breathing trouble, and may faint. You may also notice a slight blue tint to your dog’s skin. You should see a veterinary professional right away.
Tumor
Neoplasia, the abnormal growth of cells and tissue, can mean that a tumor may form in an area such as the throat, on the tonsils, or on the esophagus. A mass in these areas can cause your dog to choke, gag, and have difficulty swallowing food.
