Digestive System
The digestive system breaks down nutrients so your dog can absorb them, helps prevent toxins from entering general circulation and eliminates waste. Most digestive system diseases are reflected in familiar symptoms - diarrhea, gas, constipation, vomiting, poor appetite and weight loss. Although not illnesses themselves, they all indicate the possibility of an underlying problem. While treating the symptom will frequently eliminate the problem, you should be careful not to overlook a hidden problem.
Vomiting- This is one of the most common symptoms you will see. This makes it harder to know what is means. Occasional vomiting may be due to excitement, overeating, or digesting cold water quickly following a meal. Dogs who eat grass will also vomit. If you can see the cause, you don't need to worry. Vomiting once or twice in an otherwise healthy appearing dog is generally no cause for alarm. If your dog is vomiting and looks listless and sick or if he vomits blood, you should see your Vet.
Diarrhea- is a symptom, not a disease. You must be sure to treat the underlying cause as well. Sometimes it's something simple like a change of food, other times it can be caused by an infection of the intestine. If he has loose, unformed stools for more than a day or two, especially if he appears listless or doesn't want to eat, be sure he sees a Vet quickly. It's not unusual to see a trace of bright red blood in the stool with diarrhea. If there is a lot of blood or if its dark red, or if he is vomiting or has a fever with the diarrhea, get the dog to a Vet immediately.
For non-serious cases, withhold food and water for 24 hours. Give him small amounts of ice cubes to eat if he seems thirsty. Keep Kaopectate on your medicine shelf. Use dosages appropriate for his weight as noted on the bottle. Dunk something he loves into the Kaopectate (small pieces of chicken) and feed him until he's had the entire dose. Repeat after every bowl movement until the stool is solid. His stool may change color until the medicine is out of his system. Pepto-Bismol also works for this and nausea. It turns the stool dark.
When you feed him, give him equal parts of rice and chopped meat with the fat drained off, or cottage cheese and pasta, instead of his regular dog food until his stool is back to normal. Gradually mix dog food back into the meat/rice mixture until he's back on his normal feed. Prescription diets are available from your Vet. Check under his tail and keep the area scrupulously clean. Use Panalog if it's sore - as it almost certainly will be.
Constipation - Constipation exhibits itself as the inability of the dog to pass stool. Most dogs have a stool one or two times a day - going for two days without one is not unusual. You should get to know your dog's routine so you can see if it changes. It can be caused by poor diet, eating indigestible substances and voluntary retention. Poor diet can be addressed through Milk of Magnesia or mineral oil as a laxative and feeding a high residue diet.
Eating indigestible substances can cause fecal impaction. The dog will pass watery or blood-tinged stool, forced around the blockage . Your Vet can give the dog an enema to expel the block. Surgery might be required if nothing else works.
Voluntary retention- occurs when a dog refuses to have a stool. The dog seems to be "holding his breath" as humans do when a bathroom is not available. This is common when a dog is away from his home environment and the cues for acceptable locations are absent. A mild laxative, like mineral oil, can help lubricate the dry stool and ease passage. You should give your dog several chances a day to eliminate if you think this is the cause.
Passing Gas - You couldn't write about Bulldog digestive problems without mentions passing gas. Diets high in fermentables (beans, cabbage, etc.), milk or meat can make the condition more likely. Bulldogs seem prone to it. It's something you learn to live with. You can try a course of antibiotic therapy followed by cultured yogurt or buttermilk for a while to create "good" bacteria in the intestine.
Gastritis - Gastritis is an inflammation of the stomach lining following its irritation. Its principle symptom is vomiting. Acute gastritis is accompanied by diarrhea, which should be treated as explained above. Chronic gastritis exhibits sporadic vomiting, loss of appetite, weight loss and lethargy. You should have your Vet determine if there is some illness which should be treated or whether a change to a special diet is required.
Bloat - Bloat, or acute gastric dilation-torsion complex, is a life threatening illness. Luckily this is not frequently seen in Bulldogs. While acute gastric dilation can be treated at home, immediate response by a Vet is essential for torsion to keep your dog alive. He will have to relieve the gas or turn the stomach to permit normal digestion. Gastric dilation, and related torsion of the stomach usually, occurs in older animals and is caused by gas or fluid build-up. The symptoms are abdominal distension coupled with dry heaves - retching without being able to vomit.
