Hi,
Do you remember Dori she had 3 little white dogs all girls, I think Maltese Terriers,
the eldest girl had a lot of sensitivities & couldn’t take most flea, heartworm meds, Dori also lived in an area where mozzie where bad all year round…Dori found Sentinel Spectrum didn’t cause any side effects, with her 16 yr old sensitive girl..
Google & see does Sentinel Spectrum have the same ingredients as the Heartgard has??
Sentinel is safe to use with puppies from 6 weeks old as well as pregnant & lactating females, Sentinel might use different ingredients to the Heartgard…
Good Luck
