Commonly ivermectin is a commonly used drug to treat scabies, mange ear and also for prevention of heartworm disease (heart worm). especially poisoning symptoms may occur in dogs that are genetically hypersensitive to ivermectin or often due to an overdose of the product.

While sensitivity to this type of medication is not always guaranteed, the following breeds are more likely to be affected:

• Collie and Border Collie

• Old Inglês Sheepdog

• Shetland Sheepdog (Sheltie)

• Australian Shepherd

• German Shepherd

• Whippet

• Windhound

• Skye Terrier

It is also observed the reaction in Mongrel dogs (mongrel), older dogs who have suffered a blow to the head, puppies and dogs that may have overdosed on similar types of drugs.

Symptoms for the dog can be acute or moderate. Acute signs will manifest within 4 to 12 hours after drug administration. In mild cases, symptoms will occur between 48-96 hours after your dog has been treated. These symptoms include:

• Lethargy

• Depression

• Drooling
