Our beloved guinea pig was happy and healthy, but recently formed a growth that we had to get checked. We took her to Sager Animal Hospital for the first time two days ago, and he examined her for about 5 min, if not less, and said that it had to be surgically removed. The next day we took her in, and when we picked her up after the (small) operation she was wet, cold, and shaking. We were informed that this was normal, as Fluffy was under Anastasia, and that she would be able to get up and walk by night. We asked for more information, and they dodged our questions, not giving clear answers for the things we wanted to know. Hours later, Fluffy was not even able to sit up straight, and was crying. We tried to pet her and comfort her, and she was freezing cold to the touch. We rushed her to Tufts emergency vet hospital in Grafton and we were told that our guinea pig was not breathing. They took the care to give her medication and they put her on a heating pad to warm her up. They tried CPR for 25 minutes until we were informed that it was an extremely small chance that Fluffy would be able to survive, and if she did, she would end up brain dead. We had to pull the plug, and never got to say goodbye to our companion of 4 and 1/2 years. It was over the moment we brought her into the Sager Animal Hospital. So angry and disappointed!!! Dr. Sager may take good care of dogs and cats, but does not take his work as seriously with guinea pigs. If you have a rodent, do not bring them here! Read Less

Dr. Sager is a wonderful, extremely knowledgable and kind vet. He has treated my hamster and rabbits since about 2009, and I trust him completely (which is saying a lot because I'm VERY protective of my pets!). It is extremely difficult to find good veterinary care for "exotics" such as rodents and rabbits, and I was so relieved and grateful to find Dr Sager, who has vast knowledge of these small animals. He is calm, kind and practical, and has the patience and skill to do thorough hands on exams, so he doesn't run unnecessary and stressful tests. He has always been right on in his diagnosis and treatment of my pets. Mrs. Sager and the other staff are great too- very friendly and helpful. Also, I must mention that Dr. Water's prices are very reasonable- I am always pleasantly surprised when I pay my bill! Read Less

Dr. Sager & staff are excellent. I've been taking my rats and gerbil here. He is very knowledgeable, patient, and truly loves his animal patients. Another vet told me to put my rat to sleep. Thank goodness I went to Dr. Sager for second opinion. He saves my rat from being put to sleep for no good reason. My rat is doing MUCH better and well now. Thank you Dr. Sager!!! We greatly appreciate all you do for our pets! Read Less

A most compassionate vet. Dr Sanger is a gentle and kind human being. A wonderful person as are those in his office: Mrs Sager, Eriko, and Margie. I could not take care of my cats and dog without them. Read Less

I think Dr Sager and his staff are amazing. I drive from Ashby to Acton because I love his gentle spirit and calm demeanor. He has been treating my yorkies for 9 years. When we had to put my 17 yr old boy to sleep, he gave me the time I needed privately in a room, and it was all done with dignity. When my little girl had a lyme issue the emergency vet I took her too (it was a Sunday) gave me an estimate for teeth removal that they thought had to be done, I asked Dr. Bill to look at the bill and it was hundreds of dollars less in his office. Not only are they easier on the pocket book, the individual care and courtesy is top notch. They always return phone calls and my questions are always answered to their fullest. Thank you Dr. Bill and Staff for the great care I get for my little darlings. Read Less

I would highly recommend Sager Animal Hospital! My 1 year old dog cut her shoulder pretty bad on a post in my backyard. My boyfriend wanted to take her to the 24 hour emergency vet in Westford, MA but I knew that they would charge us an arm and a leg for seeing her. We are both young, working full-time trying to get by... we don't have $700 to spend on an emergency vet visit for stitches with a Dr. that didn't care about us or our dog. I waited until the following morning and called Dr. Sagers office first thing...I had to leave a message stating what was going on & wait for a call back from his front desk staff. Although there was a bit of a delay in receiving a call back, it did come....and not to long after I left a message. Dr. Sager was able to see me that day at lunch time & gave Harley (my dog) stitches. I was very happy with the care we received as well as the price that was charged. Two days later I got a call from the office to check in and see how she was doing. Overall, you will not find a more honest and reasonably priced vet around. I HIGHLY RECOMMEND SAGER ANIMAL HOSPITAL!! Read Less

Took a rescued macaw into the office for a checkup. I had to leave the bird to run out to the car. When I returned to the waiting room, Dr. Sager was on his hands and knees talking to the bird, and making her feel comfortable. Treatment was conservative, reasonably priced, and honest. Dr. Sager communicated well with me, and explained a lot about how to care for macaws to keep them healthy. A great avian vet. Read Less

I have gone to Dr. Sager for at least 10 years for 3 hamsters and 2 guinea pigs. He has always been informative and respectful of our pets, my children, our budget, our schedule, our values. He allowed us to be present at the death of a very sick animal, and dealt sensitively with a child's grief. I have referred friends who are dog owners to him and they have been happy with his care. It is a small one vet. operation which could explain call back issues with a previous reviewer.Read Less

Don't ever go to Dr. Sager Animal hospital!! He absolutely sucks. He or his secretaries never call back. I think they have my parents on a block list because they never answer. I called and they answered 1st ring. Finally just called an emergency hospital in Nashua and they are calling Sager's office for more info. Maybe they will get the message that we are going to switch vets. You don't treat people like this! Read Less
