Heartgard question

[wolf_Q]

I give Nebo the Heartgard chewables each month as heartworm preventative.....normally I give it on the 20th, but I kind of forgot this month and didn't give it to him until the 26th. Do you think that will make much of a difference?

I think Nebo should be fine When we got Spot, he got his heartworm test on the 20th of the month, our vet asked when the girls got their pills. Sadie is one the 1st and Cincy the 15th. He told us we could switch Spot to either date fpr the following month so it wasn't 3 different days.
