Q - Can dogs and cats get
lead poisoning? What are the symptoms and how is it treated? How can I
prevent my pet from getting lead poisoning?
A - Dr. Mike Murphy,
veterinary toxicologist at the College of Veterinary Medicine, University
of Minnesota, said vets diagnose lead poisoning sometimes once every month
or two in dogs brought to the clinic. He can recall only one cat found
to have lead poisoning in the last few years. "It certainly exists in cats,
but is not as common as in dogs," he said.
Poisonous lead can be found in unexpected places.
Pets, especially puppies, eat or chew on lead fishing weights and curtain
weights at the bottom of draperies. The solder inside electronic equipment,
such as VCRs, remotes and stereo components, is lead or lead based. Pets
may chew or swallow pieces of electronic equipment. Do not leave fishing
weights lying around and remove curtain weights until young pets are past
the chewing phase. Keep electronic equipment out of range of a curious
puppy.
Pets are at risk if they live with owners remodeling
or renovating a home that is 50 to 100 years old if they are scraping lead-based
paint off the walls, said Murphy. If you are remodeling, keep pets out
of the area until paint chips and dust are cleaned up. Until the 1930s,
some paints contained almost 50 percent lead. By 1953, the paint industry
limited the amount of lead in paint to no more than 1 percent, according
to the Minneapolis Lead Program. Lead was banned from household paint in
1978. The cat diagnosed with lead poisoning by Murphy had licked its paws,
apparently covered with lead paint chips or dust. Puppies have been known
to eat paint chips. Owners need not be concerned about a pet getting lead
poisoning by drinking water from the toilet, said Murphy.
Some of the symptoms a pet may develop after ingesting
lead include upset stomach, stopping eating, vomiting, diarrhea and blood
in feces. Lead poisoning may affect the brain and although rare, can cause
seizures and blindness. If untreated, lead poisoning can lead to death.
A pet may become lethargic or its behavior may change. For example, a field
dog that always responds to commands may become confused and not react
the way it usually does. Signs of lead poisoning may develop over a few
hours to a few days. If a cat or dog has licked paws covered with specks
of lead paint, it may take a few days for symptoms to develop. Call your
vet and take the pet to a clinic for an examination and test to determine
blood-lead levels. Many diseases and health problems can cause similar
symptoms, said Murphy. An x-ray may show a metal object in the dog's intestinal
tract which can be surgically removed. A pet also can be treated with chelating
agents, which bind the lead and distribute it into the urine to be eliminated
within a few days. The owner gives the pet injections of medication a couple
of times a day for several days. If animals that have become blind from
lead poisoning are treated, many will regain their sight, said Murphy.
"The majority of cases that are treated are successful and people get back
their normal, healthy pets," he said.
