Is my 25kg Border Collie mix overweight, or is he a healthy weight?

What a cutie! It's hard to tell from the picture, but she looks like she's at an ideal weight. Rather than tell you an exact number she should weigh, I think it's beneficial to explain what to look for to know that her body condition is ideal. At an ideal weight, you should be able to run your fingers over her sides and feel the indents between the ribs without pushing in. If you see her ribs, she is too thin. Looking down on her when she's standing, she should have a little indent in her waist. Monitor both of these things to make sure she maintains an ideal weight.

I don't tend to judge their body condition on weight as every dog is different even within a breed. I look at their body instead. They should nip in behind the ribs with a definite waist, you should be able to feel but not see the ribs, and there should not be a fat rolls at the tail. From your photo I can see Chloe has a nice waist. What you feed her sounds fine and you are well aware of what she eats.

Hello! In an ideal situation, you can feel the ribs, but not see them, so that sounds pretty good! When you look at him from above, there should be an "hourglass" shape, just behind his ribs, in an ideal body condition.

Without seeing Buddy in person (who is very handsome by the way!), I can't say if he's overweight or not because he's a mix breed dog. They can really vary in weight depending on their build and genetics. Check out this link on checking the body condition score in dogs, and that will give you an idea if he's overweight or not. You can also discuss with his vet if they feel he's overweight. I hope this helps! https://www.wsava.org/WSAVA/media/Arpita-and-Emma-editorial/Body-Condition-Score-Dog.pdf

If Loki is super active you could look into feeding a working dog diet (these usually have a higher protein/carbohydrate level than regular dog foods) or even add in a bit of a puppy formula to his daily meals for the nutrient boost. I would, however, recommend a fecal test and exam for Loki prior to switching his food to rule out any issues such as parasites, allergies, etc which can affect weight gain and may cause a normally active and healthy-eating dog to not put on weight or lose it. If he checks out healthy, then adding to his diet may help. Your vet can also monitor his Body Condition Score to let you know if he's in a healthy weight ranger currently, or where you may need to tweak it to. Most people may think their dog is "too skinny", but many breeds are naturally slim/muscular as a healthy weight and it could just be that Loki is healthy for his body type.

He actually doesn't appear to be underweight based on the pictures shown. I'd have to examine him to be sure, but the biggest indication that he is not underweight is the fact that he appears to have well-developed muscles. Dogs of this breed tend to be naturally lean and put more weight on their muscles rather than their ribs, or belly. If I was concerned that he was underweight, then I would first want to rule-out a disease, or parasite causing him to lose or not gain weight. It's best to have a veterinarian evaluate him, so you can ensure he's healthy and ensure that you are not going to feed him unnecessarily. Dog obesity is a big problem in the U.S., which means that the average person thinks a fat dog is at ideal weight; and a dog with an ideal body condition, or a lean body condition is thought to be starving. The truth is that the lean dogs are statistically healthier and live longer than overweight dogs. Some dogs (much like people) are able to naturally maintain a lean body condition. Leo is one of those dogs, but would urge you to have a veterinarian examine him to make that call. Below is a link to a body condition scoring guide. This is what veterinarians use when assessing whether a dog is overweight or underweight. We prefer them to be at a BCS of 4 or 5, but some are naturally at a 3. https://www.wsava.org/sites/default/files/Body%20condition%20score%20chart%20dogs.pdf At this time, I recommend feeding him normally and would not recommend a diet change until he can be evaluated by a veterinarian. I hope that helps and all is well with Leo.

It sounds like you are doing just fine. Dogs, especially corgis, need to be kept lean so it's good that you are being vigilant. Dogs are never too thin unless you can see all their ribs. This link may help you determine if they are at their proper weight. ( https://www.purina.com/articles/dog/health/is-my-dog-a-healthy-weight )
