Elanco Reviews 5

I am deeply disappointed by the way this matter has been handled from start to finish.

My 13-year-old Labradoodle, Bonnie, was prescribed Zenrelia after we were reassured there was no real cause for concern in switching her medication and no side effects the vet was aware of. Bonnie had longstanding allergy issues, but aside from that she was stable before starting the drug.

After only three tablets over three days, she became lethargic and seriously unwell. She then began vomiting blood and passing blood in her stools, and had to receive urgent veterinary treatment including IV fluids, sedation, blood tests and an ultrasound. It was an extremely distressing experience.

What has made this even worse is the response afterwards. Despite the clear timing of Bonnie’s deterioration immediately after starting the medication, I was left feeling that the seriousness of what happened was minimised. The explanation ultimately given was that gastrointestinal signs are recognised potential adverse reactions, yet no financial contribution was offered towards the emergency treatment that followed.

As a pet owner, you put trust in professional advice and expect proper warning of risks, especially when changing medication in an older dog. In my experience, that trust was not matched by the level of accountability, transparency or support shown when things went wrong.

I would have expected compassion, honesty and a more responsible response than this.

I am paying over $100 a month for Zenrelia for my dog. I called Elanco for some assistance as I am 72 & retired. The companies mission statement says they are all about the pets, but when it comes to a discount(not the $7 crap) but a real discount, it's all about the money they can make. I wouldn't trust this company with an earth worm!

WARNING
PETCO sells K9 Advantix by Elanco.
After using this product on my dog, I experienced serious side effects that resulted in a vet bill of over $500. Despite this, there has been no accountability or willingness to cover the costs.
These types of flea treatments work by affecting the dog’s nervous system. While they may be effective against fleas and ticks, they can also cause adverse reactions—and pet owners should be fully aware of that risk before using them.
In my experience, neither the retailer nor the manufacturer showed any concern for what happened or for the impact on my dog.
I strongly encourage other pet owners to think twice, do thorough research, and consider safer, less aggressive alternatives before using this type of product.
