Guys I need advice, I got my lab at 12 weeks, he is growing into a beautiful black lab, yet he has always seemed to be picky about his food, but only recently he refuses to finish his breakfast. As soon as he sees us having dinner etc.. he is sat near the table thinking we will give him a bit of our food, which we don't by the way. He doesn't have any other symptoms such as diarrhoea or vomiting, he is always full of energy. We exercise him few days a week, but he gets tired so quickly after few laps around the park. We would come back home and he is so worn out he just sleeps and pants heavily. After some time it stops and it back to normal. I have booked an appointment with the vet this Thursday, but wanted to see if any of you had a similar thing with your dog.
