If a dog suddenly goes from being a great eater to a mediocre eater or starts skipping meals I am usually concerned that there is an underlying medical issue. In Soska’s case specifically, this change in appetite and behavior may be due to the fact that at 9 months of age her rate of growth is beginning to slow down and she may not need as many calories as she did when she was growing much more quickly. I would continue doing as you are now, meal feeding her and removing the uneaten portion of food after giving her 15-20 minutes to eat it. Feed her at least twice daily. If her appetite continues to drop off and this behavior persists for more than a week or so, I would recommend taking her in to see your vet so you can be sure there are no medical issues going on. I hope this helps. Best of luck. Thanks for using Petco Pet Education Center, formerly Petcoach.
