So the males pretty much filled out huh? Good to hear. Some handsome shepherds here in the forum! I'm just a little upset right now, my boy has been refusing to eat for a good 2 weeks now, I've been hand-feeding him throughout his meal times.. It was really sudden. Checked to the vet; he's totally fine physically (so that's $65 out of the window), so it's a behaviour issue. Have tried everything pretty much: add some broth, wet food, changed the brand once (ate the new food at first, now back to No No). He used to be so crazy about his meal time. He still eats if I give out the kibbles as 'treats,' but never from the bowl. He hasn't gained any weight in a month, for the 1st time since I got him at 2 months (now he's 10 1/2 months). Just talked to our trainer this morning, looks like I've come to my last resort: gonna put down the bowl for 15 mins, if he doesn't eat, well too bad you're gonna be hungry. My trainer said once she had to do it to her dog, the dog gave in after 3 days. So I'll see what happens then. It's very upsetting as an owner. Times like this I wish us humans can communicate with animals through language. Wanna let him know how lucky he is to have a home and to be fed twice a day premium food, whilst so many other dogs don't have the luxury. Just a little too agitated I suppose, that he's being difficult and ungrateful for food with so many other living beings would kill for it. I don't believe I've ever been so disappointed in my dog. First for everything they say.....
I'm not much help in terms of the weight and height gain, as my girls only 7 months old.
I might have a few suggestions for the food because my hound/shepherd(?) mix has the same issues. He ended up losing a lot of weight in the shelter then started gaining, but all of a sudden lost quite a bit. Which in terms of weight was fine because he was a bit overweight but his sudden lose of appetite was unsettling. We tried over 5 different brands of food with zero change in appetite after 2 or 3 days of eating it.
What we found that worked was changing him to a high quality food which was stinky and smelly. We chose Orijen for this purpose (averages about $40 a month since he's not very active and is only 60-65 pounds.) But I know there a quite a few high quality (smelly) foods that don't get nearly that expensive.
Then we add pumpkin (he loves the stuff) which works really well for him, he hasn't missed a meal and we're on his 2nd bag. So pretty good for our major picky eater. We previously had tried adding his favorite treat (string cheese) 100% pork and beef and regular canned dog food plus way more. He wasn't interested until we switched to the Orijen and pumpkin combo, now instead of missing meals or walking really slowly to eat he comes up really quickly and eats.
I think the major reason he stopped eating was because of stress. When he was at the shelter he way underweight due to the constant barking and motion (other dogs) at the shelter, he's very much a non vocal (by choice) coach potato so I think it was to much. Then when we got Olivia a few months later (profile pic) he again went off of food.
So it's possible that if your dog is anything like our Murdoc he could be stressed out and just not wanting to eat. Our maybe just changing up there diet to something else that smells could work, seemed to do the trick with Murdoc.
If your dogs lose of appetite bothers you could try to give a beef knuckle or other such meaty treat. That way your dog has at least something in their stomach. However there is that fine line between getting a dog to eat and rewarding them for being picky so that's something you want to gauge.
Picking up Murdoc's food never worked for us, that's why I mentioned this. He would just flat out starve himself and go days without even a nibble. However I know a few dogs that picking up the food trick has worked for, just not ours
