Have used First Sheild on my 2 small dogd and had no problems at all. All the other, more expensive flea/tick applications i used before are no longer effective.
Ticks can be a problem in my area during summer so i am glad my dogs have no adverse reactions to this product. My neighborhood Banfield vets have been good pet health care providers and are the only affordable option around. However, they are best for primary care.
If your dog has a serious illness or injuriy take her/him to a reputable, full service veterinary hospital. Expect the specialized care to cost a lot more.
