Can you imagine the damage on a small dog's little heart.
Are they painful for dogs?
Discomfort in the least I'd think.
I want to say gross, but sad is all I can really think.
The prevention, in conjunction with regular testing is so inexpensive verses both the treatment and suffering.
If given the option to heart-worm prevent or flea/tick prevent I'd choose heart-worms prevention-and parasites that can affect humans are my personal phobia.
I think a video like this should be mandatory in a part of pet ownership requirements-seriously I beleive we as a society should have a pet ownership certification required.
I find it ironic this is the next video that popped up as an option to watch-VERY GRAPHIC! Animal cruelty pup mills 90 severely neglected Yorkies.
