My 4 year old miniature horse licks me uncontrollably. For the first few months I thought it was cute and that she was just “kissing” me but it’s been almost a year and a half now and she’s done it since the day I got her. I’m beginning to think it’s a vitamin/mineral deficiency. She has a salt lick and uses it so I don’t think it’s salt. Ive been researching a few different supplements but I’m not really sure what to be looking for because I’m unsure of what causes it. She will lick hands,legs,shoes,clothes,your back, anything she can get! Any suggestions or similar cases?
