Hi pawbly friends.... One of our GSD, Butch, is in his twilight years, approaching 14. It has been very eventful here with the addition of two new GSD rescues since July, and there have been some scuffles, but everyone is managing great now. All the “teething troubles” seem to have been worked out. When we lost Butch’s best bud, he stopped eating and lost about half of his body weight. The rescues kind of helped put some pep back in his step and he is doing great. He’s still underweight, but not like before. My question is, I’m worried about preventatives. With so much of him gone, I’m afraid to give him his dose of parastar, but I also fear Lyme disease, especially given his age. Being that it isn’t winter, I hate to admit, I haven’t been giving him his dose. Now that spring is around the corner, I am more concerned about ticks because of the warmer weather. Thoughts on preventatives? Should I give a lower dose? Regular dose? Every other month? I’m just worried because he is compromised enough and underweight, but Lyme is also very serious and would be awful for him as well. Any advice is very appreciated. Thanks!
