6. when dog attack or mouth the large, slow moving toads.
When threatened or handled, it secretes a highly toxic
milky substance from its large parotoid glands at the back
of its head, behind the ears. This secretion can burn your
eyes, may irritate your skin, and can kill cats and dogs if
they ingest the secretion.
A dog can die following a single exposure, morbidity is high
Habitat:
Exposure:
In united states mainly in Florida and Hawaii
It was originally released in the U.S. in sugar cane fields to help
control “white grubs,” larvae of pest Scarabaeidae.

7. Cardioactive glycosides
I. Bufotoxin
II. Bufotenins
have digitalis like and oxytocic (vasopressor) actions.
Other are
Epinephrine
5-Hydroxytryptamine
Principle Toxin:
 in pets include excessive salivation ,drooling, head-
shaking, crying, loss of coordination,
 in more serious cases, convulsions, The dog's (or cat's)
gums often turn red, an indicator used by veterinarians
to distinguish toad poisoning from epilepsy.
Symptoms of poisoning:

8. MOA of Toxin:
The toxin are produced in the parotid gland ,
Toxin absorbed by the mucous membrane of dog
Excessive stimulation by the cardioactive glycosides
causes ventricular fibrillation and hypertension

9.  No specific antidote
 Flush the mouth of pet with stream of water
 Detoxification with activated charcoal and osmotic
cathartic.
 cardiac arrhythmias can be controlled by giving
propranolol at 2mg/kg.
 Atropine can also used to control salivation and
brocnhoconstriction
Treatment
:
Laboratory
findings: Hematology changes increase level of PCV,
 Increase level of glucose, BUN,
 Hyperkalemia and hypercalcemia
 Decrease in leukocytes count
