  • Responsible Dog Ownership

    A good read to put the lifelong commitment of dog ownership into perspective.
  • I was thinking…

    It looks so nice and green outside! My dogs love it too, they can't stop eating all the new shoots of GRASS! My boys have had no dietary changes, no symptoms of illness, and a lot of the time, they are not vomiting the grass.
    Grass is just something that dogs enjoy to eat!
    When I catch my one dog chewing at some grass I command "find!" which means to find a toy, oh the beauty of distraction! My other guy seems to start munching if he is left outside for too long without mental stimulation. I cut bathroom breaks shorter, or sit out with him and monitor.

  • The Ticks are here!

    I've even had a tick on myself already! My dogs are vaccinated against Lyme disease and currently using Bravecto from April-September. I will deworm at the end of the season with Drontal Plus.
    This decision and plan was based on our lifestyle and recommendations from our veterinarian during their annual physical exam.

    Parasites are here!

    Cats are requiring parasite prevention and treatment as well! My cat, who frequents outside in a "catdio" (a safe outdoor enclosure) is fully vaccinated and will be on Revolution from May-September and will receive Milbemax at the end of the season as dewormer. This decision and plan was based on his lifestyle and recommendations from our veterinarian during his annual physical exam.
