The shift you have made in your own health that now has you seeking ways to overall improve your health rather than merely getting rid of each symptom or illness is the same philosophy you need to apply to your animal friends. Again, there is no one right method of treatment. Some (although very few) animals just do not like acupuncture needles, some animals do not exhibit the characteristic idiosyncrasies we need to best prescribed homeopathically, some need the energy support of Reike or therapeutic touch or Zero balancing to be the most healthy. Most will improve with any well-done treatment.
Again, like the above question, the only person qualified to answer this question in your particular case is your doctor. There is a very good reason that you can’t buy “TRT kits” at the drugstore, its because there are a lot of issues to be weighed to know if the health benefits of TRT outweigh the risks of going on TRT and only a doctor is qualified to determine that. Having said that, in general terms, as I say in the answer to question 1 “Is TRT Legal”, TRT is used to treat some serious symptoms. The advantage of TRT is that it reduces or eliminates those symptoms. It will also help re-gain (not gain) muscle mass that was lost. What are the disadvantages? Again, discuss the health risks with your doctor but three indisputable disadvantages are: 1) the cost, 2) the inconvenience and 3) the fact that you would be on the medication for life.
