Hi everyone I’m new here, just wondering if anyone can give me some advice on walking my 9 years old golden retriever. Ever since we asked our tenant to help us look after our dog because of a family trip, he’s gotten used to helping us walk Fido (our dog) everyday when he goes for his everyday hiking exercises without asking for anything in return. Should I still walk Fido after his (half to one hour) walk with our tenant? Will it be too tiring for Fido because I think our tenant is starting to play with him as well (sometimes). We don’t really have a problem with him walking Fido because our family members all go to work and used to only walk Fido around twice per week, so we think what he is doing is actually nice for Fido. I am the only student in my family, and I think right now I can start to take my dog with me to the library everyday, so therefore walking him at the same time. Will it be too much for Fido because he is almost 10 (2020)? And also, how long can I leave Fido outside the library unattended? Also he is very gentle and friendly so will it be safe to do so?
