Almost an immediate improvement!

My girl is 14 and has had a mild heart murmur for the last few years, recently though she had developed ‘the cough’ that comes with an aging heart and I felt helpless

My girl is 14 and has had a mild heart murmur for the last few years, recently though she had developed ‘the cough’ that comes with an aging heart and I felt helpless watching her suffer. I started her on these supplements and it was almost an immediate improvement, after a few days her coughing went from waking us up repeatedly through the night to being nearly nonexistent. She’s been taking the chews 2x a day for almost a month now and is no longer coughing during the night, I’m so grateful.

This helped my senior dog with mild heart problem

He had lots of energy from them. All the neighbors noticed. Now he's 16 and 4 months, sadly, he won't eat them any more. He's picky in his old age. But for awhile

He had lots of energy from them. All the neighbors noticed. Now he's 16 and 4 months, sadly, he won't eat them any more. He's picky in his old age. But for awhile they made him jump and run.

Great for the heart

My girl has heart murmur, and I searched for a heart supplement that might help her heart. I picked this brand because of the ingredients that are natural and known

My girl has heart murmur, and I searched for a heart supplement that might help her heart. I picked this brand because of the ingredients that are natural and known to be good for the heart. After taking it for a couple of months, my girl was at the vet, and the vet listened to her heart, and commented that her heart sounded like it is better. yeah! Looks like these supplements might have helped.

Good heart supplement

Dobby has a heart murmur and vet suggested adding a heart supplement. I have used this one in the past. Dobby won’t take as a treat but it’s a soft chew and easy
