My lovely Penny just turned 1 and is suffering from ibd. She’s (8kg) 18lbs and height is 42 cm. I just washed her and even though her blood work shows that all her numbers are fine I’m concerned about her weight even though the IMS says she’s fine. Having a hard time to bulk her up. She is exclusively on royal canin hypoallergenic small dog, 150g a day. What do you think?
