    Staph Infections

    By on

    Firstly, I can't comment if this is the right drug for your dog's health issues. That recommendation is strictly between you and your vet for your pet's care. My GSD has been having recurring staph infections and this medication isn't quite expediting recovery as intended. We are trying one more round for longer duration, but her skin isn't reflecting signs of total recovery. So that's discouraging but staying cautiously optimistic maybe we'll turn a corner soon. On a side note, this medication takes a while to receive so just be mindful of that with the level of urgency required to start Rx for your pet.

    Broken Jagged Bottle

    By on

    I was highly disappointed when I received my prescription for my furbaby when I twisted the white cap off the blue bottle was broken and jagged. Which made me think, when filling up my bottle why didn't they see the bottle broken and it was sharp jagged edges. Highly disappointed and upset. Sincerely, The Alvarado Family
