Update in OP; Treating young lab for heart worms

Despite being on preventive heartworm pills all of her life, our 2 1/2 year old lab has heartworms. Anyone every gone through this treatment process?

We've decided we need to do it, but thinking about the fact that she has to stay in a crate/kennel for about 8 weeks other than going for short walks and for the bathroom seems cruel. She is very hyper and will chase a tennis ball all day long. Can't imagine seeing her sit in a kennel day and night.

We're fearful that she may die during the treatment from getting too excited when we walk up with the leash to take her outside.

Anyone got experience with this?


UPDATE
She got the first injection 2 weeks ago. You could tell she didn't feel well for the first say or two. She's on prednisone as part of the process due to some other mite issue. She's pretty much back to acting normal now. Her water consumption has increased tremendously. We bought her the 4 x8 kennel below for her to have some extra room. The shed is air conditioned and we pull he kennel out on nice days.

We also let her out for 5-8 hours a day just so she can lay around. All the neighborhood kids have been to not to play with here or throw balls to her. So far so good. We get the next two injections in 2 weeks. After the next injection we will be less likely to leave her out to lay around as that's when I'd think the clot issue most likely may come into play.
