... Heart worms are "A"-symptomatic ... get the Dog blood tested as soon as possible!
There are often no visible signs a dog has contacted hw til they collapse. This is why yearly testing/preventative is so important. Keep dog tested & on meds & you won't have to worry.

Lethargy, deep cough, and generally lack of apatite, and that's a sever case. A dog can show no signs of the disease in light or mild cases. If you suspect your pooch has heart worms have him/her tested NOW! It can and will kill if not treated!!
