Thank you for taking such excellent care of Toby during his recent chemotherapy. We are enjoying every minute with him!


It was ‘under the weather’ but my paw is a lot better thanks to you. Thanks for being so kind when I was a scaredy-cat.

Erich, Leih & Jack

Thank you so much for taking care of Jack. We are very thankful that you were able to catch the problem in time and save his life. Your patience and willingness to help is much appreciated. Jack is doing much better. We will see you soon.

It was with great emotion and sadness that during the evening hours of 1/15/10 I had to bring to your care five innocent victimis of neglect.

Words cannot express the satisfaction and appreciation that you have given me in regard to not only this unfortunate case, but also in every animal that is brougt to your attention by me and Marshfield Police Department. You have always welcomed us with open arms for the good of animals. On the night of 1/15/10 there were no hesitations. The doors of the Castlerock were opened, staff was brought in, and love poured out. I personally want to thank every last one of you for everything that was done for these dogs.
