Hey everyone, three months ago my family became the proud owners of our first Bernese Mountain Dog. His name is Reggie and he is the sweetest dog. I have a few questions, I would like to get some opinions on: 1. We got him from Petland and he has Gardia. We our on our fourth round of antibiotics... Need answers on if there is something else we can do for him, and if this will ever go away! He is 5.5 months old and only 44 lbs, not sure if thats the Gardia or if there is anything we can do to get him bigger? 2. Secondly I have been researching when to get him neutered, not wanting puppies from him. Everything I have read has said 1 year to 18 months, our vet said 6 months to avoid aggressive tendencies? What are your guys opinions? 3. Last, looking for good food recommendations! Thank you guys in advance!
