The Collie is usually quiet unless there is a reason to bark. However, if he is left alone too often or is bored, he will bark excessively.
Both varieties require grooming, but the Rough Collie needs extra regular brushing to keep its coat clean and tangle-free.
#1 Many Collies are sensitive to medications, including ivermectin, a substance found in heartworm preventatives.
Talk to your veterinarian before giving your collie a heartworm preventive or other medication.
#2 Be careful who you buy a Collie from.
The collie's popularity has increased the number of unethical breeders who don't care about temperament, health, or conformance.
