Cryptosporidium can cause profuse, watery diarrhea with cramping, abdominal pain, and nausea in both animals and people. Illness in people is usually self-limiting and lasts only 2-4 days, but can become severe in people with weakened immune systems.
Cocoa within chocolate contains theobromine, a chemical stimulant that, together with caffeine and theophylline, belongs to the group of methylxanthine alkaloids. Dogs are unable to metabolize theobromine effectively. If they eat chocolate, the theobromine can remain in their bloodstreams for days, and dogs may experience fast heart rate, severe diarrhea, epileptic seizures, heart attacks, internal bleeding, and eventually death. “One ounce of milk chocolate per pound of body weight is a potentially lethal dose in dogs.” In case of accidental intake of chocolate by especially a smaller dog, contact a veterinarian or animal poison control immediately; it is commonly recommended to induce vomiting within two hours of ingestion. If chocolate ingestion is suspected (mostly dark or baking chocolate), hydrogen peroxide can be used to safely induce vomiting, then making a trip to the veterinarian is suggested. Large breeds are less susceptible to chocolate poisoning, but can still die after eating four ounces of chocolate.
Mouse and rat poisons containing cholecalciferol cause hypercalcemia and hyperphosphatemia in dogs. Clinical signs include depression, loss of appetite, vomiting blood, weakness, and shock. Treatment is as above for recent exposure. When hypercalcemia occurs (which can take 1 to 2 weeks), treatment is with intravenous fluids (saline), diuretics, corticosteroids, and calcitonin. Long term prognosis is good once the dog is stabilized.
Mouse and rat poison is commonly found in the house or garage. Dogs readily eat these poisons, which look like small green blocks and are very attractive to them. The poisons work by depleting stores of Vitamin K in the body, without it, blood cannot clot properly. Clinical signs of poisoning include depression, weakness, difficulty breathing, bruising, and bleeding from any part of the body. These clinical signs often take 3 to 4 days to show up. A blood test will show that the blood is not clotting properly. If the poison has only recently been ingested (within 2 to 3 hours), the dog should be given apomorphine or hydrogen peroxide to make it vomit. Activated charcoal can be given to absorb any remaining poison in the gastrointestinal tract. Then the dog is given Vitamin K supplementation for 3 to 4 weeks, depending on the type of poison. At the end of treatment, the clotting times should be tested again. The prognosis is good in these cases. However, if the dog is already showing signs of poisoning, it is too late to try to remove the poison from the body. A whole blood transfusion or plasma is given to treat the anemia and to try to control bleeding. Vitamin K is also given. The prognosis is poor in these cases.
The first symptoms in people can start days to months after exposure and include generalized weakness, fever, and headache. Within a few days symptoms will progress to confusion, anxiety, behavioral changes, and delirium. If you have been bitten by a dog or other animal and feel that there is a risk for rabies, contact your health care provider right away. Once symptoms appear, it is almost always too late for treatment.

Developmental orthopedic diseases include panosteitis and hypertrophic osteodystrophy. Panosteitis occurs in large and giant breed dogs usually between the age of five and fourteen months and manifests as fever, pain, and shifting leg lameness. Hypertrophic osteodystrophy is also seen in young large and giant breed dogs and is characterized by pain, lameness, fever, and swelling of the long bone metaphysis.

You need a heads-up on potential health problems and their risk factors, so you can prevent them altogether. Well, here it is: the most common yet preventable dog diseases, along with expert advice from California veterinarian Dr. Nicole Eckholm of the Pet Emergency and Specialty Center of Marin.
Heartworm is a parasitic worm that lives in the heart and pulmonary arteries of an infected animal. The worms travel through the bloodstream—harming arteries and vital organs as they go—ultimately completing their journey to the vessels of the lung and the heart chamber about six months after the initial infection. Several hundred worms can live in one dog for five to seven years.
Tetanus* is a disease caused by the bacteria Clostridium tetani following wound contamination. Dogs are not very susceptible to tetanus. Signs include difficulty opening the mouth and eating, contraction of the facial muscles, and rigid extension of the limbs. Dogs may also get localized tetanus, signs of which include stiffness of a limb spreading to the rest of the body.
Kennel cough is a term loosely used to describe a complex of respiratory infections—both viral and bacterial—that causes inflammation of a dog’s voice box and windpipe. It’s a form of bronchitis and is similar to a chest cold in humans.
What to look for: Thankfully, rabies is not as common today as it once was due to the development of vaccinations, but it is still possible for your dog to become infected with rabies even if he has received his shots. Symptoms of rabies include heavy, thick drool and aggressive behavior.
Avoid bites and scratches from dogs. Dog bites might become seriously infected or might be a source of rabies. Be cautious with unfamiliar animals. Approach dogs with care, even if they seem friendly.
People exposed to Salmonella might have diarrhea, vomiting, fever, or abdominal cramps. Infants, elderly persons, and those with weakened immune systems are more likely than others to develop severe illness.
It is important, however, not to get overly worried by this as the percentage of dogs in the UK who have contracted this disease is truly minuscule. Though, what is vital, is that you understand the problem and know what to look out for, should your dog come into contact with it, as time plays a large part in successfully treating the disease.

Echinococcosis is a parasitic disease caused by eating or drinking food and water contaminated with a specific type of tapeworm eggs or through contact with an infected animal. Dogs become infected by eating tissue of an infected animal. Dogs rarely show any signs of disease, but if they are infected with a large number of worms, dogs can have diarrhea and enteritis.

Certain breeds are more likely to develop particular tumors, larger ones especially. The Golden Retriever is especially susceptible to lymphoma, with a lifetime risk of 1 in 8. Boxers and Pugs are prone to multiple mast cell tumors. Scottish Terriers have eighteen times the risk of mixed breed dogs to develop transitional cell carcinoma, a type of urinary bladder cancer.
What to look for: Since there are so many kinds of allergies dogs can have (from food to flea/tick bites and a wide range of other possibilities), it’s important to look for any change in behavior when exposed to something new. If your dog goes a few days showing lack of energy, has a consistent cough or sneeze, or if anything else seems out-of-place, you might be dealing with allergies.
“He is soooo cute,” you thought when you first laid eyes on your dog. And—yay!—he seemed to like you too. So you brought him home—only to realize that maybe you weren’t totally prepared for the work this relationship involved. Well, your mom was right (again): Owning a dog IS a big responsibility, from training to feeding to keeping it stress-free. “We don’t have that many years with our dogs,” says Whole Dog Journal editor Nancy Kerns. Here’s how to make sure each day is filled with health—and happiness for you both.
“If you think your dog is too skinny, it’s probably the right weight,” Case say. Dogs with excess weight are more prone to joint problems and diabetes, among other health issues (sounds familiar). How to tell if Fluffy is chubby? “It’s all about the feel,” she adds. “Ribs shouldn’t be visible, but easily felt.” Tip: Rub your hands up and down your dog’s flank. You should feel the ridges of its ribs without having to push in to find them.
How to treat: A steady diet and regular exercise are the two things needed when your dog is overweight. It’s important to recognize the severity of your dog’s obesity and be sure to administer the right changes in nutrition and exercise. Too much exercise, or too significant a reduction in food, can cause other issues, so you should consult your vet before making any drastic changes to the diet.
