As a hunter at a disadvantage without a pet, I found the following are helpful in many of the mount-in-training fights (in particular when you are trying to do the achievements Advanced Husbandry and The Stable Master, which increase damage taken by the mount). Possibly some *slight* overkill, but you can pick and choose which method you prefer:

1. 
   
2. Using Dual Talent Specialization, choose [spell=155228] as the level 100 talent of one of your two specializations (both Marksmanship and Survival have this talent). [spell=155228] will add 30% to your damage without a pet present, which makes the fights go much faster, especially when you have to do 36 mount-in-training battles in a row for an achievement.
   
   (Note: switching between specs is very quick if you have never done it before. It doesn't cost you anything, and it is always useful to have a second spec set up. There is no need to dismiss your hunter pet to make [spell=155228] activate - it activates when you get on the mount)
   
   
3. 
   
   
4. Create a Mend Pet macro to heal the mount-in-training:
   /cast Mend Pet
   Note: the Mend Pet spell in your spellbook won't work because it changes to Revive Pet when you summon the mount.
   
   
5. 
   
6. The level 45 hunter talent Exhilaration is also very useful (particularly in the case of [npc=87107]), as it heals the mount for 100% (verified).
7. 
   

Do not summon your demon, hunter pet, or water elemental - you will be dismounted.
