Bloat is the common name for gastric dilatation and volvulus, or GDV. It's often fatal, and happens more often to large dogs. The stomach fills with gas and distends, which is called dilatation. It then twists into an abnormal position (volvulus). This twisting pinches the esophagus and small intestine openings, which traps food and gas in the stomach.
Twisted blood vessels and the enlarging stomach hamper the blood flow, causing the dog to go into shock. Left untreated, the dog will die from shock or a ruptured stomach.
Hot spots are the common name for acute moist dermatitis or pyotraumatic dermatitis. Hot spots are hairless spots on the dog's body that are red and oozing. They seem to pop up on the skin overnight.
Hot spots usually start with an allergic reaction or other condition. The resulting severe itch or irritation starts the dog licking it constantly, until he licks it raw.
Common causes are allergic reactions to flea bites or other bites, other allergic reactions, skin parasites, chemical irritants, and skin infections.
MG is weakness caused by signals from the brain not getting through to the nerve receptors in the muscles. There are two forms of this disease.
The inherited form is a problem with either too few receptors in the muscles, or malformed receptors. The symptoms are muscle weakness and regurgitation due to the esophagus not working properly.
The other form of MG develops later in life, when the immune system starts to attack the nerve receptors in the muscles. Symptoms include leg weakness that worsens with activity and then improves with rest and/or a short, stiff gait. Weak facial muscles and megaesophagus are sometimes seen as well. dog health issues glossary
A series of blood vessels that surround the esophagus and constrict it, causing regurgitation problems. Seen most often in German Shepherds and Irish Setters. Treatment includes surgery to remove the unnecessary, abnormal blood vessels.
