My pony that I've had 9.5 years turned 30 this past October and both myself and my mom have noticed she's not keeping weight like she used to. The vet just came out tonight and gave her a look over for me and said she was on the skinny side but said it was just because she was older now. Right now I feed her three times a day- Morning ( about 5:30 AM), when I get home from school (about 3:30) and Night (7 pm ). Would a senior feed help her gain weight? My mom isn't big on supplements because they cost so much but I'm wondering if they might help her gain and keep more weight on. Any ideas?
