The way Collies operate makes it a bit difficult to appoint a measured portion to them. A smaller portion size of a meat-based diet with less grain is an accepted feeding mix for most Collies. As much as possible, avoid corn and soy ingredients in their meals.
Be observant of how they feed. Do they eat up what you give or are they always remaining some on their dog bowl? This would give you a little insight into their feeding portions. Remember that your Collie is prone to GDV, a stomach condition from fast eating or drinking which can be fatal.
To be on the safe side, just consult your vet doctor at the very beginning of your foray with your Collie, various meal plans would be developed by him or her for your dog but your observation of how your dog eats would help you to better manage conditions which crop up from overfeeding like Obesity, Diabetes, GDV, etc.
Collie dogs are known to be heavy shedders with the rough-coated ones shedding more than the smooth-coated ones. Getting their hair brushed weekly is recommended. A good thing about the Collie is that they are naturally clean dogs so they may not require regular bathing.
Bathing them every two or three months is ok as far as they don't get into messy situations within that period.
Routine grooming activities are advised e.g dental routines, ear cleaning, nail trimming, etc.
The Collie get five stars for their ability to be trained easily. They are always eager to learn and obey. The caution here is not to be too strict or harsh while training them. They are sensitive dogs and hence any harsh treatment would be perceived in a negative light leading to bad results while training them.
A naturally active breed, the Collie does well with daily exercise, especially when it comes with some mental stimulation. Daily walks, games like fetch, aerobic exercises, anything that can give them a chance to run around and play is welcome. Living in a fenced compound would do them good here, else exercising in the public park (with a leash) would be the next option.
Just keep in mind, a neglected Collie would get mischievous and destructive in time. It is simply better to give them some company and find ways of engaging them mentally. They learn and become useful members of the family and everyone is happier for it.
Although the collie is a generally healthy dog. They are still prone to some health conditions as follows
Gastric dilatation-volvulus (GDV) - This usually occurs due to the twisting or bloating of the stomach from fast consumption of food and water. A general precaution is not to overfeed them and to contact a professional anytime you observe any stomach problem.
Progressive retinal atrophy - An eye problem that can lead to loss of sight if not properly handled
Collie eye anomaly - usually a birth defect which can be easily managed by following a vet doctor's recommendation.
MDR1 gene mutation - This health problem is a reaction to various drugs which they have been given for example some collies don't do well when placed on ivermectin( a well-known heartworm medication)
